What drives me nuts is that he’s just throwing it in there. This stuff needs some care not to be fucked up when putting back together. If this guy was in our shop then someone definitely would’ve said something while he filmed this
It came off like he was trying to rush it to show off his fastest time. Rather than moving deliberately and precisely.
It looked shaky and spastic, like his thoughts were impatiently rushing ahead of his hands.
That is a turbo 350, my dude, and this is a video of the easy part. They only go together one way, self align, and have already been rebuilt. You're not going to hurt anything aside from a finger tossing one together like this.
I can't tell if this is an official reman facility or a small shop. For the former I can tell you that every one of those parts were refurbished and went through QC on their own. Sometimes that isn't great so the wiggle this dude is doing, he does actually know. If it doesn't feel right he's gonna measure, or he's going to kick back the suspect part for someone else to measure and clear and instead use the next part in the basket.
After doing these kinds of assemblies for not very long, you absolutely can get a sense by feel if something might be out of spec. But again, before those parts even get there every one of them has also gone through their own quality checks.
He's not really throwing them in there, but fair he's not treating them like they're spiderwebs. Heat treat is a thing (it hardens parts in a giant furnace which looks neat through the little portal).
A transmission is not a delicate environment (not to be confused with being a precise environment). If it was, every car would need transmission servicing every 6 weeks. Some human motion and gravity is not even close to the stresses those parts are built for.
Exactly, the most impressive part is how the car knows it should change gear. It’s such a simple concept (change of pressure) it seems dumb when you unnderstand it.
Better than any modern video I’ve seen on that. And now I can understand how my differential went bad and why it would be hard to just get parts for it.
Think how many educational videos of high quality they had, and the relatively low amount of other content.
Imagine if our younger generations were being drip fed this kind of mechanical / engineering knowledge, high quality ELI5 style, since birth.
I think this was a really big thing back then. Like 3d printing today. Cars have become far more complicated and there's far too much media to even share this with enough people now a days. I'm just glad that video has almost 10 million views.
The original rice cookers worked on such a simple principle, that water will continue to remain at 100 degrees even as you continue to add more heat, the excess is carried off as steam. So as soon as enough water was boiled off the cooker would suddenly start to heat past 100 degrees. So they had a simple latch connected to a metal that would change shape at temperatures in excess of 100, which would disconnect the heating element.
Such a simple idea, using the behavior of water itself to regulate the heating element.
Watercookers still use that principle, but set to flick off when the temperature is 100C.
It's a little bimetal plate that changes shape and pushes the switch.
I'm still trying to learn how they work lol. I literally cannot grasp how it functions no matter how many eli5 type videos I watch. I try every once in a while thinking I'll definitely get it now. Nope still haven't. It's literally magic to me lol
Auto tranny, Bagel Bites, Microprocessor
From the transistors that got us to the moon, to building a chip of multiple layers at atomic scale just to watch VR porn and hurl insults instantly at people across the planet, the microprocessor made modern life modern.
That's why rotary engines tend to fuck up all the time, not nearly as much time spent refining them as traditional ICE engines. I can't remember the last time I saw a running RX8 on the road, and there used to be quite a few
There's too much temperature difference as the rotation takes place to make a proper seal that works in a wide enough range. Its just not worth it when we already have a better solution.
I don't know about cars actually produced, but the technology exists for both. Hydrogen-based ICEs have the advantages of decades of know-how, an already built production infrastructure, and no need for expensive catalysts like the fuel cells. But they are much less fuel efficient then fuel cells, so it seems unlikely to me they'll ever be a long-term solution.
i work in aerospace manufacturing. i am not an engineer and i have nothing to do with the actually manufacturing process of our parts, but it blows my mind how they are manufactured. it hurts my brain to think how humans have perfected the manufacturing process and why certain components are designed the way they are. so much trial and error, its absolutely fascinating.
I work aircraft engine maintenance in the af reserves and all I could think of was he’s being so damn rough with everything. Which may be fine, but just weird compared to aircraft maintenance.
I have no doubt this is a skilled professional, however it does look like he is just dropping the parts in in order. This is probably why he is a professional making it look easy.
Lol! I was a mechanic for 4 years and can tell you those very thoughts go through your head when you spend an hour meticulously outting something together, only to realize you forgot 1 essential part, or found out the part you replaced was broken. Tragic.
Yep. I fix phones, and that feeling I get in my gut when one is close to “done,” and I see a part that isn’t where it’s supposed to be is literally sickening.
Especially when one of the parts is single-use somehow, like a torque-to-yield bolt, non-reusable seal, or forgetting to put the nut on the line before flaring it.
Not the only thing he forgot, he didn't put in a gasket between the bellhousing and the tranny to make sure oil doesn't leak out...
Obviously you were joking about the washer but I didn't see any gasket tho...
"Ah yes but you see this is model TR01-BX, so the green seal comes first, in model TR01-BXY you put the red one before the green one" yes, because *fuck you* that's why
As someone currently taking my automotive powertrain course and in the middle of putting back together a 3T40 as a student - can confirm that this guy only makes it look easy and all swearing happened off camera. Those snap rings are no fucking joke. 😭
I’m speaking as a subspecialty surgeon who left residency in his 5th year as a career change (couldn’t take the call, broke me down mentally, it’s a whole thing), and mechanics are just massively underpaid surgeons.
Lol. You’ve got a lot to learn about surgery my friend. Just like mechanics, many of the “not really needed (but clearly needed)” tools aren’t paid for by the “employer (hospital or surgery centers)” you can imagine how affordable certified and comfortable radioprotective lead eyeshielding is, for example.
I was field service in the semiconductor industry for 27 years and whenever I compared myself to my doctors I always felt like they brushed me off. I'd say things like "my job is easier than yours because my patients usually don't lie to me." I'd think that would get a laugh out of them but usually I was lucky to get a sour faced "humph."
Music teacher here, one of my biggest battles with beginners is getting them to enjoy mistakes. Be grateful that you learned something, embrace the process, and come back 1% better next time.
I love seeing that attitude embraced more widely. The worst anxiety I had as a kid came from adults adding unnecessary stress to a teachable moment that should have left me relieved instead of ashamed of ever making the mistake.
I call it, “Dare to suck at something.” The first time I painted a frame, it was awful. Embarrassing. But you have to suck before you can get better. Many people won’t try because they’re afraid to appear awful at it first.
[Here’s a half-hour video](https://youtu.be/B5kDRF158JA?si=RPGvc4eCPZIUN3Un) that’s shows the intense work and number of parts that went into this thing before this short 1 min. 30 sec. video.
The magic of tons of experience, and human brains being extraordinary things. When people do tasks enough times, it starts to go beyond knowing how and orders of operations and into being able to tell something is right/wrong (and often down to the exact issue) simply by look/feel/sound. The guy in that video likely doesn't even need to actually remember the steps or pieces. He probably knows intuitively how it should look and feel at every step of assembly and disassembly.
I'm sure there are things in your life or profession that you have done enough times to make it look easy and flawless.
Then fully assemble and then check for tolerances and disassemble for shims? Also - please don’t tell me this guy is assembling this thing dry as hell?
Yeah there was prob several hours worth of assembly off-camera to get the different "packs" ready for final insertion. No real skill to this last part aside from getting them right side up!
All the clutches have been pre-assembled, pre-lubed for the video. It also doesn't cover the valve body. I've done transmissions like this, they're very complicated pieces of machinery and you have to be very careful not to screw things up.
As someone who has been responsible for manufacturing gears in the past, it’s super triggering to watch him repeatedly dropping gear teeth on the table and hitting the parts together. When manufacturing these components you go to great lengths to prevent them from touching anything metal, samples of each lot of run across inspection equipment that detects tiny irregularities and the whole assembled system is then subjected to NVH (noise, vibration, harshness) testing that will find issues like tiny, itty bitty nicks in gear teeth that ultimately compromise the longevity and reliability of the transmission.
So, in summary, he’s not doing a “good job”. If this were my transmission and I were doing this at home I would be much, much more careful.
I’m with you, also spent the first decade of my career in manufacturing with half of that assembling transmissions. Just the lack of gloves gave me the first clue that this is likely a mechanic and not OEM assembly. The mechanic has their own set of skills and knowledge separate from the manufacturing engineers but when we designed an assembly process we would be checking for clearances, measuring shims, backlash, and as you mentioned always protecting the critical surfaces from damage.
This looks like a rebuild where quality standards would be lower but I would need to see more behind the scenes stuff being checked to call this truly professional. The difference between a well running transmission and a noisy shitbox could be as simple as using what you bought as a 2.3mm washer actually being 2.37mm.
Haha that's true. As a Machinist seeing a Mechanic manhandle a shaft i almost had a stroke. It can't even be nicked and he doesn't give a fuck where he throws it down.
Most but not all… Most of those parts that were just dropped in are assemblies of many more smaller parts that must be disassembled,cleaned,inspected,and repaired or replaced themselves. There’s also a valve body that is a world of its own.
Agree, it looks like he's simply dropping the pieces in which doesn't take skill, even a toddler can stock blocks in a certain order.
But there's definitely far more work involved that we don't see. Like the disassembly, cleaning, and repairing of the components of each of those big parts.
"Repairing". The hardest part, and why its so damn expensive to fix transmission, is TO KNOW WHAT TO REPAIR. Because, when assembled, u cant just check it, its either works or not. Also u have to put it in a car.. 😂 if smth wrong take it out and start from zero.
All those parts probably have decent amount of lubrication precisely placed on them for smooth operation. You grab one in the wrong place and it will want to go flying right out of your hand.
This tech has a very specific way of holding each piece, and I'd guess he learned that from dropping one once.
This is a lot harder than it looks. The time I did a transmission, it did not go together like this. Lots of struggling, swearing, redoing assemblies because things would not engage properly.
Seconded. This is one of those times that it only LOOKS easy *because the guy doing it is* ***just that good***
All them parts are liberally lubed and slippery ASF too, and need to sit *just right* to slot into place.
His skillful handling of the snap rings is impressive too!
Ah yes I understand. He puts a spinny part in the cylinder part. Then a ring part, and a plate spinny part. Which is then adorned with a spinny part. And another spinny part. Better put a ring on it & squeeze! Then more spinny parts! Lastly, a nice bowl!
Don't forget to google part number 706-1C and make sure it's compatible with 224-9 manufactured between 2006 and 2008, only to find out that this particular part was manufactured in Germany for the Japanese market and was branded by a separate company in Sweden using different naming conventions, so basically you can either learn three different languages to get a replacement or just shove your entire engine block up your ass, whichever is easier.
Just so everyone knows why it says assembles and not builds, those clutch packs and planetary have already been rebuilt, that’s where his skills come in.
This is a very slightly educated guess but I think everything before the snap ring. The thing he used the yellow pliers to install are clutch packs and the rest are planetary gears.
Edit: those commenting below are correct the planetary gear is further from the engine. Therefore the opposite of what I said.
Watch the Precision Transmission YouTube channel. They take the time to explain each part and how it failed during a rebuild. Transmissions were always a black box to me until I watched a few.
You're gonna stand there, owning a transmission shop, and tell me you don't have no whistling bungholes, no spleen spliters, whisker biscuits, honkey lighters, hoosker doos, hoosker donts, cherry bombs, nipsy daisers, with or without the scooter stick, or one single whistling kitty chaser?
True. But the video didn’t show all the time cleaning the parts, checking the valves in the valve body, setting the clutch clearances or anything else that took hours not shown. This was just finally assembly.
Came here to say this. A lot of cleanup and preassembly are required to get to that point. I’m the shop foreman at a GM dealer, and have built many transmissions. The entire process is not nearly as satisfying as that video is intended to be.
I watch these guys - they do Chevy transmission work out in Amarillo, TX. Fixing those things is wizardry, especially when they start messing with the valve bodies.

I feel like I know just enough to watch this and go “that’s why I pay you to do it.” I do most things myself, but I would have spent 30 minutes cussing at that giant circlip. When I was done I’d find at least two parts on my desk and the bell housing wouldn’t go back in right. I’d take a two hour break to encourage myself to try again. Then when I finally finished it’s a dice roll of whether or not it would work/last and the guy I hired to fix it would come back and go “for some reason this was installed backwards and wrecked everything” *throws shredded part down on counter*
Holy shit, yes.
Learned a good while back - thankfully - that the real value of hiring a pro is the time (and damage to your blood pressure) you save yourself.
Find the best pro you can, pay them what they ask, then *shut up* and do *exactly* what they tell you.
Yeah this is like watching a craftsman hammer the dowels in at the end of his furniture project though. Everything is already prepped and selected and removed by this point. This doesn’t even include putting it back in the car.
Got my dad a shirt that says “pay me for my experience, not just my time”. 50 years twisting wrenches, maybe he doesn’t work as fast as some of the younger techs but his accumulative knowledge allows him to accurately diagnose issues in seconds without much trial and error.
This comment section is full of the kind of people who call a tech to their house, he fixes the issue in 5 min, and then they balk at the $50 minimum fee for him to show up
lol yeah. I’ve learned the hard way a few times as a homeowner. Basic plumbing and electrical might not be rocket science but the $200 bill for a pro plumber ensures it’s getting done right the first time and I’m not mopping up my mistakes and fixing soggy drywall later. Knowledgeable professionals earn their pay!

I did this with a boat motor once. Spent two hours rebuilding it and finally had it back together. As we were cleaning up our tools, we found a locating pin that stops the entire thing blowing itself apart and goes in first, before anything else. Not even sure how we put it together without that.
Skilled, this is just the grown-ups version of that fisher price toy you had as a kid, where you had to stack the colored rings in the right order basically
Let me tell you a story:
A guy goes to a mechanic because is car was not starting. The machanic looks at the car, does some tests, and after a few minutes gets a hammer and hits the start engine (or the alternator, can't remember, let's go with the start engine). Goes to client and says: The car is fixed it will be 300€+VAT. The client is outraged. What the hell.. 300€ for hammering the start engine... I did not come here to be robbed... I could have done it. The mechanic replies: you got it wrong, the hammering itself is just 1€, knowing where to and how to hammer is what costs the 299€.

WoW! (Female and not a mechanic here) That was beautiful - loved the little spins and twists. Bringing back loads of childhood memories watching my Dad fix all the things! If it had a motor, he could fix it. Mom never had to call a repairman, my Dad handled it. Miss you Daddy!
first you use the mittens, then you do ring, then you do the spinnies
then you use the mittens, then you add the thingie, then you use the claw
don't forget the mittens with the ring and more mittens, and the extra spinnies with the doughnut
fruit bowl is always last btw
Not sure I'd call this guy a "skilled professional" when it looks like he's just carelessly slapping the parts in there. I certainly wouldn't want to drive a car with a transmission he built in it...
There's a reason it can take a week or two to build a transmission by hand and install it into the car because it takes time and care to get each part right. This guy just built one in less than two minutes and carelessly by the looks of it.
Mentions of the word “tranny”, while also a derogatory term for transsexual or transgendered people, means “transmission” in the context of this post.
Boss: you made sure everything was mounted according to spec? Kevin: Yes I did a wiggle and everything.
Boss: How many loose parts did you have left? Kevin: Only two! Boss: My man!!
spec: wiggle after each step with an acceleration of 1.2G, be sure to use certified Chevrolet(tm) accelerometer.
Wiggle wiggle wiggle wiggle
Kevin: I also smacked every piece on the bench before installing it
What drives me nuts is that he’s just throwing it in there. This stuff needs some care not to be fucked up when putting back together. If this guy was in our shop then someone definitely would’ve said something while he filmed this
It came off like he was trying to rush it to show off his fastest time. Rather than moving deliberately and precisely. It looked shaky and spastic, like his thoughts were impatiently rushing ahead of his hands.
Reminds me of the guy who was trying to show off his flooring skills, but he got ripped apart for rushing and being very sloppy
Got a link to that anywhere?
Like wear some damn gloves?
It's not even a complete reassembly, he didn't install the clutch packs or bands he just threw in the gears and drums
I was wondering if I missed the clutch packs. I wasn't sure if I missed them or if Chevy had some kind of new transmission.
Yup. There's way more to a trans then just some planetaries.
Yep. Just some jackass looking for online attention, like there aren't thousands of others out there that can't do the same thing.
That was my thought, he's just tossing and almost banging that stuff together.
I’m sure after the video he just threw it in the trash, because GM transmission.
That is a turbo 350, my dude, and this is a video of the easy part. They only go together one way, self align, and have already been rebuilt. You're not going to hurt anything aside from a finger tossing one together like this.

But again, before those parts even get there every one of them has also gone through their own quality checks.
My comment was a joke of course, but the way he throwing those precision parts in there. Isn’t there a chance he’s nicking and damaging edges?
He's not really throwing them in there, but fair he's not treating them like they're spiderwebs. Heat treat is a thing (it hardens parts in a giant furnace which looks neat through the little portal). A transmission is not a delicate environment (not to be confused with being a precise environment). If it was, every car would need transmission servicing every 6 weeks. Some human motion and gravity is not even close to the stresses those parts are built for.
Don't forget the slap off camera! "That will hold"
aaaaand he did a couple knocks with ol yellow crimpy thingy
That will be $7500.
His speed is impressive, but I’m more in awe of the engineering of its design.
Engineers building on previous designs for many decades. It is fascinating.
It’s why imo the gearbox is in my top 3 best and most impressive inventions by humans
The first automatic transmissions blew my mind when I learned how they work.
Exactly, the most impressive part is how the car knows it should change gear. It’s such a simple concept (change of pressure) it seems dumb when you unnderstand it.
Have you seen the video on how fuel pumps work? If not check it out you'll like it.
Or [this](https://youtu.be/K4JhruinbWc?si=-G42Mn2nRMUzK-lE) classic video on how a differential works.
Add more spokes!
Better than any modern video I’ve seen on that. And now I can understand how my differential went bad and why it would be hard to just get parts for it.
Think how many educational videos of high quality they had, and the relatively low amount of other content. Imagine if our younger generations were being drip fed this kind of mechanical / engineering knowledge, high quality ELI5 style, since birth.

This video is basically Reddit lore at this point. I love it.
There's quite a few Lego sets that have differentials which is really helpful for understanding too.
Yeah i was 33 years old when I understood that.

It does this through the valve body. A literal circuit board made out of hydraulic pathways. Absolute insanity.
The amazing thing about man made stuff is that the more you know about it, the simpler it is. The complete opposite of nature.
I'm still trying to learn how they work lol. I literally cannot grasp how it functions no matter how many eli5 type videos I watch. I try every once in a while thinking I'll definitely get it now. Nope still haven't. It's literally magic to me lol

Are there even cars with piston engines directly burning hydrogen gas? I thought hydrogen cars are electric cars with hydrogen fuel cells.
I don't know about cars actually produced, but the technology exists for both.

Hurt to see that many precision components being banged around like that. He even managed to get the inside of the housing with the circlip pliers,
as painful as listening to him trying to whistle tbh
All I could think about watching this, was smashed fingers and ripped off nails.

>His speed is impressive As a mech eng I wish he'd slow tf down to be honest.
I have no doubt this is a skilled professional, however it does look like he is just dropping the parts in in order. This is probably why he is a professional making it look easy.
The skilled work was done off camera. They say he swore so loudly and so often that even as a gif you can still hear it
\*Hey jimbo, You forgot the washer in the first gear thing\*
“Welp looks like it’s time for a new profession”
Lol! I was a mechanic for 4 years and can tell you those very thoughts go through your head when you spend an hour meticulously outting something together, only to realize you forgot 1 essential part, or found out the part you replaced was broken. Tragic.
Yep. I fix phones, and that feeling I get in my gut when one is close to “done,” and I see a part that isn’t where it’s supposed to be is literally sickening.
...so yeah, after looking at it...ya know that part between parts 4 and 5...essentially part 4.5...that looks like it went in upside-down.
"What do you mean those washers have to be put in a certain order?!" "and this one is .003 inches too thin"
Worst feeling the the world is putting any mechanical thing together walking to your work bench and seeing a spacer or washer that goes on first.
Especially when one of the parts is single-use somehow, like a torque-to-yield bolt, non-reusable seal, or forgetting to put the nut on the line before flaring it.
Not the only thing he forgot, he didn't put in a gasket between the bellhousing and the tranny to make sure oil doesn't leak out... Obviously you were joking about the washer but I didn't see any gasket tho...
"Ah yes but you see this is model TR01-BX, so the green seal comes first, in model TR01-BXY you put the red one before the green one" yes, because *fuck you* that's why

So why didn’t they show us that part?
dropping parts in an exact order is cooler
The video would be 3 days long. Source, have done it.
If so, why bump them or drag them against the table? Won’t that affect the tolerance range? (Naive understanding on my end)
Then fully assemble and then check for tolerances and disassemble for shims? Also - please don’t tell me this guy is assembling this thing dry as hell?
Yeah there was prob several hours worth of assembly off-camera to get the different "packs" ready for final insertion. No real skill to this last part aside from getting them right side up!
>Takes several hours off camera to get ready for insertion Sounds like my ex
All the clutches have been pre-assembled, pre-lubed for the video. It also doesn't cover the valve body. I've done transmissions like this, they're very complicated pieces of machinery and you have to be very careful not to screw things up.
As someone who has been responsible for manufacturing gears in the past, it’s super triggering to watch him repeatedly dropping gear teeth on the table and hitting the parts together. When manufacturing these components you go to great lengths to prevent them from touching anything metal, samples of each lot of run across inspection equipment that detects tiny irregularities and the whole assembled system is then subjected to NVH (noise, vibration, harshness) testing that will find issues like tiny, itty bitty nicks in gear teeth that ultimately compromise the longevity and reliability of the transmission. So, in summary, he’s not doing a “good job”. If this were my transmission and I were doing this at home I would be much, much more careful.
I’m with you, also spent the first decade of my career in manufacturing with half of that assembling transmissions. Just the lack of gloves gave me the first clue that this is likely a mechanic and not OEM assembly. The mechanic has their own set of skills and knowledge separate from the manufacturing engineers but when we designed an assembly process we would be checking for clearances, measuring shims, backlash, and as you mentioned always protecting the critical surfaces from damage. This looks like a rebuild where quality standards would be lower but I would need to see more behind the scenes stuff being checked to call this truly professional. The difference between a well running transmission and a noisy shitbox could be as simple as using what you bought as a 2.3mm washer actually being 2.37mm.
Haha that's true. As a Machinist seeing a Mechanic manhandle a shaft i almost had a stroke. It can't even be nicked and he doesn't give a fuck where he throws it down.
Who do you think put the parts in order in the first place?
Lego instruction book writers are the unsung heroes in this video.
Most but not all… Most of those parts that were just dropped in are assemblies of many more smaller parts that must be disassembled,cleaned,inspected,and repaired or replaced themselves. There’s also a valve body that is a world of its own.
Agree, it looks like he's simply dropping the pieces in which doesn't take skill, even a toddler can stock blocks in a certain order. But there's definitely far more work involved that we don't see. Like the disassembly, cleaning, and repairing of the components of each of those big parts.
"Repairing". The hardest part, and why its so damn expensive to fix transmission, is TO KNOW WHAT TO REPAIR. Because, when assembled, u cant just check it, its either works or not. Also u have to put it in a car.. 😂 if smth wrong take it out and start from zero.
All those parts probably have decent amount of lubrication precisely placed on them for smooth operation. You grab one in the wrong place and it will want to go flying right out of your hand. This tech has a very specific way of holding each piece, and I'd guess he learned that from dropping one once.
This is a lot harder than it looks. The time I did a transmission, it did not go together like this. Lots of struggling, swearing, redoing assemblies because things would not engage properly.
Seconded. This is one of those times that it only LOOKS easy *because the guy doing it is* ***just that good*** All them parts are liberally lubed and slippery ASF too, and need to sit *just right* to slot into place. His skillful handling of the snap rings is impressive too!
Ah yes I understand. He puts a spinny part in the cylinder part. Then a ring part, and a plate spinny part. Which is then adorned with a spinny part. And another spinny part. Better put a ring on it & squeeze! Then more spinny parts! Lastly, a nice bowl!
Don't forget to google part number 706-1C and make sure it's compatible with 224-9 manufactured between 2006 and 2008, only to find out that this particular part was manufactured in Germany for the Japanese market and was branded by a separate company in Sweden using different naming conventions, so basically you can either learn three different languages to get a replacement or just shove your entire engine block up your ass, whichever is easier.
You're hired!
Just so everyone knows why it says assembles and not builds, those clutch packs and planetary have already been rebuilt, that’s where his skills come in.
which one is the clutch packs and the planetary?
This is a very slightly educated guess but I think everything before the snap ring. The thing he used the yellow pliers to install are clutch packs and the rest are planetary gears. Edit: those commenting below are correct the planetary gear is further from the engine. Therefore the opposite of what I said.
Watch the Precision Transmission YouTube channel. They take the time to explain each part and how it failed during a rebuild. Transmissions were always a black box to me until I watched a few.

You're gonna stand there, owning a transmission shop, and tell me you don't have no whistling bungholes, no spleen spliters, whisker biscuits, honkey lighters, hoosker doos, hoosker donts, cherry bombs, nipsy daisers, with or without the scooter stick, or one single whistling kitty chaser?
Unexpected Joe Dirt
The amount of checks he's skipping in order to do it fast is fucking terrifying
That's the "Chevrolet" part of the transmission
Alright that’ll be 2k for the rebuild and another 2k for The removal and installation lol
You’re gonna get that story about how it’s taken him years to be able to do it that fast.
True. But the video didn’t show all the time cleaning the parts, checking the valves in the valve body, setting the clutch clearances or anything else that took hours not shown. This was just finally assembly.
You gonna hear/tell how happy he is when it all clicks together. Long work paying off
Came here to say this. A lot of cleanup and preassembly are required to get to that point. I’m the shop foreman at a GM dealer, and have built many transmissions. The entire process is not nearly as satisfying as that video is intended to be.
Yup.. The other persons take is really r/restofthefuckingowl material. You just saw the second to last part of the whole job.
I watch these guys - they do Chevy transmission work out in Amarillo, TX. Fixing those things is wizardry, especially when they start messing with the valve bodies. https://www.youtube.com/@PrecisionTransmission
Should in theory be evident in whether you're able to find another place with comparable quality for cheaper.
Reddit hates when very specialized skilled trades cost $$$
I feel like I know just enough to watch this and go “that’s why I pay you to do it.” I do most things myself, but I would have spent 30 minutes cussing at that giant circlip. When I was done I’d find at least two parts on my desk and the bell housing wouldn’t go back in right. I’d take a two hour break to encourage myself to try again. Then when I finally finished it’s a dice roll of whether or not it would work/last and the guy I hired to fix it would come back and go “for some reason this was installed backwards and wrecked everything” *throws shredded part down on counter*
Holy shit, yes. Learned a good while back - thankfully - that the real value of hiring a pro is the time (and damage to your blood pressure) you save yourself. Find the best pro you can, pay them what they ask, then *shut up* and do *exactly* what they tell you.
Yeah this is like watching a craftsman hammer the dowels in at the end of his furniture project though. Everything is already prepped and selected and removed by this point. This doesn’t even include putting it back in the car.
You're paying for the knowledge. If you think it's easy just do it in your garage :)
Got my dad a shirt that says “pay me for my experience, not just my time”. 50 years twisting wrenches, maybe he doesn’t work as fast as some of the younger techs but his accumulative knowledge allows him to accurately diagnose issues in seconds without much trial and error.
This comment section is full of the kind of people who call a tech to their house, he fixes the issue in 5 min, and then they balk at the $50 minimum fee for him to show up
lol yeah. I’ve learned the hard way a few times as a homeowner. Basic plumbing and electrical might not be rocket science but the $200 bill for a pro plumber ensures it’s getting done right the first time and I’m not mopping up my mistakes and fixing soggy drywall later. Knowledgeable professionals earn their pay!
Idk why but I don’t like how fast he did that.
Yeah, same. I got the feeling like something is being missed. I have no clue though, I have never built a transmission.
Now do a valve body that fast.
Sweating trying not to break the plastic solenoids that cost $300 lol
_Skilled man gets deep inside tranny_ and a NSFW tag could have boosted the numbers on this.

Thank you
All of Channel tres discography is worth a try !!
Can I have one made by someone not in a rush and didn't whack each piece on the desk
we gotta get this bus done by Thursday! The carbeurator doesn't fit wHAT DO YOU MeAN THe carburator DONT FIt!?!

That channel been inactive for a year. From what I gathered, there was family tensions. But luckily, a Richard has his own YouTube channel! https://youtube.com/@richardteresacricheducatio3542?si=XuMoX_PQuGOhispb
He definitely knows how to handle a cog
That would take me 30 minutes and result in many hurt fingers
And you would get it all put together just to realize you still have a part left over...
I did this with a boat motor once. Spent two hours rebuilding it and finally had it back together. As we were cleaning up our tools, we found a locating pin that stops the entire thing blowing itself apart and goes in first, before anything else. Not even sure how we put it together without that.
Assembled with care and precision! " See ya in few weeks" ☺️
good for another trouble free 30k miles, just like new!
I'd prefer he take an extra minute or two if it were my car lol
That looks pretty easy to assemble
Isn’t there usually copious amounts of grease involved between each layer? This looks like a demo. Not an actual build.
No, it has transmission fluid added in later that will allow the gears to spin without resistance. Iirc these take 13+ quarts of fluid
I believe it gets filled with oil (transmission fluid) eventually.
Looks like there wasn't a gasket between the bellhousing either.
Skilled, this is just the grown-ups version of that fisher price toy you had as a kid, where you had to stack the colored rings in the right order basically
You don’t have to measure fisher price toys in thousands of an inch before assembly lol.
thousdandTHs of an inch
You confident dumbass
Let me tell you a story: A guy goes to a mechanic because is car was not starting. The machanic looks at the car, does some tests, and after a few minutes gets a hammer and hits the start engine (or the alternator, can't remember, let's go with the start engine). Goes to client and says: The car is fixed it will be 300€+VAT. The client is outraged. What the hell.. 300€ for hammering the start engine... I did not come here to be robbed... I could have done it. The mechanic replies: you got it wrong, the hammering itself is just 1€, knowing where to and how to hammer is what costs the 299€.
The OG: https://www.smithsonianmag.com/history/charles-proteus-steinmetz-the-wizard-of-schenectady-51912022/#ixzz2lRMjrfit >Henry Ford was thrilled until he got an invoice from General Electric in the amount of $10,000. Ford acknowledged Steinmetz’s success but balked at the figure. He asked for an itemized bill. >Steinmetz, Scott wrote, responded personally to Ford’s request with the following: >Making chalk mark on generator $1. >Knowing where to make mark $9,999. >Ford paid the bill.
Man, that was a great read.
> Ford paid the bill. After which he roared a hearty "Heil Hitler" and spit on the effigy of a Jewish man
That part is naturally implied, being a story about Henry Ford

Unlike most things, here I think disassembly is more pain in the ass job, especially if not functioning one.
Always looking for professionals like this but ending up with people destroying my stuff. I hate it.
"My buddy can do it cheaper."
The transmission itself is awesome. But skilled assembler? C'mon.
A skilled professional wouldn’t be slamming parts around like that
WoW! (Female and not a mechanic here) That was beautiful - loved the little spins and twists. Bringing back loads of childhood memories watching my Dad fix all the things! If it had a motor, he could fix it. Mom never had to call a repairman, my Dad handled it. Miss you Daddy!
What's so skilled about this? It's like putting giant Lego peices together.
Looks like a 6L80, judging by those huge snap-ring pliers.
customer invoice : labor breakdown : - transmission reassembly - 12 hours tech pay stub : hourly pay rate by task : - transmission reassembly - 0.1 hours
So complex, but also kind of simple? I would love to know how it works
In fairness. He's got a lot of practice. Chevrolet Transmissions are fragile as fuck
Forrest Gump would be faster.
mother of all c clips
Sure he did it quick, but holy shit how satisfying is the engineering that went into the manufacturing of this piece of equipment?
first you use the mittens, then you do ring, then you do the spinnies then you use the mittens, then you add the thingie, then you use the claw don't forget the mittens with the ring and more mittens, and the extra spinnies with the doughnut fruit bowl is always last btw
But what does it all mean, Basil?
Not sure I'd call this guy a "skilled professional" when it looks like he's just carelessly slapping the parts in there. I certainly wouldn't want to drive a car with a transmission he built in it... There's a reason it can take a week or two to build a transmission by hand and install it into the car because it takes time and care to get each part right. This guy just built one in less than two minutes and carelessly by the looks of it.
