A lot of people here are complaining about how the video doesn’t explain how it works, it’s not supposed to, the show is called “How It’s MADE”

Suddenly all the GM transmission problems make sense; just look at the amount of fucks not given during assembly.

Not one part pre-lubed!

I'm in an automatic transmission course right now and, man, once you understand how these things actually function its pretty amazing. Engineers can do some awesome things.

That video didn´t make me any smarter. Now I even have more questions.

This episode was filmed in the General Motors Transmission Plant in Windsor, Ontario. My dad worked there at the time and remembers them filming haha

Transmissions don't last long, but their blocks sure do last forever. 1979 El Camino, original 305. Still going strong.

Great informative video. Excellent video. Regards,

After watching this 10 times.... I now understand.

This video has just reminded me why I drive a manual... :)

This is amazing. Thanks for posting. Amazing how complex these transmissions are. I am sure you will agree that transmissions are some of the most complex things made by humans. The number of components that must be precision-made and interconnected are awe-inspiring.

WOWWWW, GREAT VID, I HAVE TO HAVE MY TRANS RE-BUILT!!! :-(

Its good, i feel i learned a lot especially from my drivetrain class. I graduate june 09.

Every time I watch videos on automatic transmissions I want to put a manual transmission into my car.

I was lost after "the transmission in your car......" lol and i was so willing to learn!

Damn I had no idea transmissions were so complicated. The level of complexity in a transmission is insane.

Many people think the engine is the most complex item in a car. Not even close. When you think of all the hydraulics and gear sets, clutches, solenoids, and all the other components that must work in perfect harmony...the transmission is the king of complexity, hands down. Like the coasting clutch. It allows the car to coast at low speeds, and brakes you at higher speeds. How? I have no idea, but I do know that it must work perfectly of the car will be undrivable. Amazing.

omg thinking the same thing! I had a feeling I wasnt the only one effected! lol

For anyone who is interested this unit is a 4t80e. It comes behind the northstar in cadillacs. It is a very hd unit but still has problems with the torque converter clutch wearing out.

It is amazing to me that these small notches, grooves, and other components can withstand 300+ WHP. Very interesting....

Bring on the electric car revolution. One motor, one planetary reduction gearbox, and one battery pack. No gear changes, no clutches, no stick shifting :)

Nice explanation about automatic transmission.

I love engineering but I will never understand how an automatic gearbox works. And this video didn't help. Annoyingly.

It consists of magic and friction and a lot of clutches, I shall join too of not fully understanding how it works. I still prefer having a regular gear box and 1 clutch, manual gear shifting isn't to hard when you learn how to do it effectively. Then again America has to be different than the rest of the world.

EFLCModder It's actually pretty simple, but there are various ways of transfering power from the crankshaft to the wheels. Older systems uses brake bands, the newer ones use cluthes. The shift control is the same hydraulic system. If you think of the auto transmission as a 5 speed manual gearbox with a clutch for each gear acting as the gear lever in a manual and the hydraulic system as the driver shifting, you are not far off how it works.

Stefan Asmussen Thanks Stefan. I have to say that this is the best explanation I have ever heard that's describes the principles of an automatic gearbox. I shall be remembering this for a long time. Did you know that cars with auto boxes in the UK tend to one or two brackets higher road fund licence than the same car with a manual box due to their inefficiensy as UK road fund fees are based on emissions.

Nice Demonstration !! I feel lot of effort and work is done in order to bring our car in running condition....Nice Job all Engine & Car Manufacturers.......

It's simple in concept. You have gears to set a gear ratio. (Planetary gears) You have a clutch, not so different from a manual clutch. You have a torque converter. And you have synchronizers on the gear assemblies. In an auto, you simply have MORE gear assemblies, controlled by hydraulics. There are some really good online animations showing how it works. Nothing is complicated, it's just that there's a lot in the case. But only some of it is active at any given time.

Fuck this, I'm glad I have a 6 speed manual

DjRjSolarStar I thought the same thing. Not only are these things hard to fix, they're hard to explain, period, without some passing knowledge of engineering.

I abslutely loved it.

thanks to who have made and think about all of these.

Now I know how it's made ! :D

@reddot44 some had vacuum, like the zf 4hp`4, or was it 3hp14, while my current 4hp18 just uses ATF pressure and rotation speed of a govenor on spring weights, throttle position is sensed by a variable pressure feed

Anybody know of a video from the manufacture that takes you thru the complete process of a transmission all components and tools used as well as the time it takes to pump out how many transmissions per hour say

@tayedrummer14 You will only find a fly wheel on a stick shift (manual transmission). As Tayedrummer14 said, it smooths out engine pulses and is used to retain kinetic energy. But it is also used to start the car. Along the edge of the fly wheel, are spokes, alot like a cog, which is connected to the starter motor. When the starter motor receives electricity from the generator or battery, a little cog in the starter moter turns, which in turn turns the fly wheel, starting the engine.

This is actually a transaxle, which is a transmission and differential in one integrated unit. Mostly used for front wheel drive cars, though some rear wheel drive cars use one to help with weight balance.

With the appropriate configuration, the continuously variable transmission CVT Edyson can transmit any ratio, with high efficiency (more then 95%), so even (or more) then 4:1. Naturaly that will increase a little the volume of the gearbox.

Hats off to the engineers :)

This woman narrator knows so much about Transmission.

@0123Brock It's because the more splines (the notches and grooves) you have, the less pressure is on each groove. It's divided up between them. Up until a point that is. And by the way, most can't handle 300+ WHP without upgrades. They're generally designed to barely handle what the engine puts out from the factory.

These transmissions are a lot simpler than they used to be because of computer control. They used to have an extraordinarily complex hydraulic servo system which controlled everything.

that went right over my head.

@radoslavnikolic Yea lots of stuff but the basics is the hydralics fluid sent by the computer is what tells those clutches what to do. And those clutches in turn control there set of gears and that tells that the car what to do! Automatic transmissions are more complicated and therefore more expensive but they make driving a lot easier!

Everyone should watch. See how fragile a transmission is. Drive easy, make it last!

That wobbly screw is a TapTite Screw. It is a self tapping screw going into a hole that it not tapped. The wobble is just the way it goes in and taps its own hole. It was new technology back in 1993 when the 4T40-E was designed and is now standard procedure now. There were many innovative things on the 4T40-E and was GM's World Class transmission till it stopped production as the 4 speeds were phased out in 2010. I worked there for 31 years and started when we built the TH-350 then the 3T40.

yet the best marvel available on cars. LOL when I was in NY driving, past year... I was once again thanking GOD for automatic transmission! XD

@fenixans Is a 4T60E chevy one

They forgot to add the most crucial pert of all... the Kanuten Valve, which, in conjunction with the Turbo Encabulator, allows the car to operate properly. Next, we discuss the importance of checking the Blinker Hydraulic Fluid... and the other critical components, including the Tire Pressure Compensator Relay...

@dotcombatgames I would say go for it, the more knowledge you have the better off you are. Transmissions by themselves are as complex as the engine itself. They aren't all that complex in the grand scheme of things, but it would be good to know and understand how things work with each other. You may never work on a transmission, but it helps so much to at least understand both the engine and transmission and what they're doing together. It will help you understand why certain things are so.

how are some auto transmissions able to shift gears faster?

I found an old automatic transmission under the house as a teenager, gee I had fun pulling it all apart, but putting it all back together well.......took 5 times longer, but I learned heaps. The narrator refers allot to electronics in this clip, but electronics still need mechanical interfaces, like how does the electronics ascertain the hydraulic pressure in each segment of the transmission?

According to the website, this was filmed at GM's Windsor, Ontario transmission plant.

@APontiacof455cubes is towing max capacity only for the tranny not the chassis and engine, like the 4l80e has more

i used to work for aplace that made transmissions and the transmission cases were made out of magnesium alloys i have allot of magnesium scraps still

And in regards to drag racing, you are absolutely right, in a straight line, when simply accelerating, a computer can shift much faster then a person. But track cars, such as grand prix, touring, and F1, are usually in someway manual. very few still use the classic "H" pattern shifter, but most have gone the route of the sequential manual (gear up/gear down) because it allows them to enter a turn in the correct gear. Automatics are "reactive" and Manuals are "proactive"

Those transmissions are used in the daewoo cars and gm cars. I have a lanos and it's still pulling hard with only 94.000miles on the clock! ;)

GREAT ONE THX

@liltstan the auto will be useful if you are driving from newyork to washinton

@ItsMrWinters I don't know what German car you have been around that breaks. My 1989 bmw 750 has almost 300,000 miles and the transmission changes fine. Plus it has had a lot of abuse from the big V12 powering it.

Holy S&@;! That's complicated, it definitely a sophisticated piece of machinery

it is easy to understand once you have worked on one! automatic transmissions are very different and hard to understand I am an agricultural mechanic too!!

@kakureru i was talking about the actual car's transmission. basically when it shifts into a higher gear it takes allot more effort to bring car to speed. The manual version is worst..

That is actually GMs 4T45e trans. The vehicle at the end is a chevy HHR

I make those plates at 2:30 its kinda cool to see how there used.

@mpreztwomx Hahahaa. Im pretty sure both the front tires turn. If just one turned i think the car would just go in a circle

i cant drive stick :( i have tried on several different occasions but its just to hard to focus on the road and change gears

@truenolz maybe some of us can't afford manual cars. ever think of that?

79 Cutlass, 0 problems.

@soco13466 - ah the Kanuten Valve mmm that explains a lot. Thanx

what they show in the beginning of the vid is a transmission but, aren't they building a trans-axle?

@0123Brock it is not HP accounts for the real power. Torque is the stress on parts that should be accounted for true measure

@gtuabc I could tell it was gm because of the bellhousing bolt pattern

What's really crazy is how little difference there really is in these modern units, and the GM hydramatics produced in the 40's. Obviously the electronics, but the fundamentals are the same.

thank you so much

I guess the factory doesn't soak the friction clutches or fill the converter on assembly.

What about the third option?: I just got a kit from TCI for 500 bucks, and rebuilt my 4L80-E into what they call a "streetfighter", which they sell for over 3 grand. Funny, this vid is about a transverse engine, front wheel drive car... but all the pieces are recognizable and comparable to my trans in my truck. If you are a trans tech, you are a wizard !

A 4L60E is one of the best automatic transmissions there is. They are used for drag racing all the time. It's an extremely durable medium-duty transmission. There is a reason GM has been building them for over three decades.

And yet - watching being assembled there, it looks a bit cheap.

what do the fast cars use at the dragstrip?

If you ever se a manual transmission being disassembled you will surely understand how they work :P and some automatic transmissions use 2 sprockets where one (the drive sprocket) has weights in it an will expand when it spins fast enough that means that the higher the speed the sprocket spins the higher the transmission ratio.

@yvesttt so what if they use more gas? they are bigger and have more power :)

Wow lol. That sounds fun though. It's a great field to get into. I love cars. So how is it? Did you graduate?

Just know not all automatic transmissions function the same. Honda automatics work more like manual transmissions that are controlled automatically. The internals favor a Honda manual transmission. 5 minutes isn't long enough to really explain how they work, but the video did a good job focusing on the main point. Hyrdraulics that are controlled electronically. Without fluid it is a hunk of metal.

True. One thing i've noticed from watching "how it's made" on the Science channel. Is that they actually TRY to make it sound as complicated as possible. That, and the fact that they only have a few mins. to explain the topic at hand. So almost definitely something is going to get left out. This is one of those things thats easy to understand, but hard to master. I have a college degree in Automotive.

@yvesttt the number one car in gas mileage is the Chevy Cruz Eco actually. 42mpg

That's actually the same 6 speed automatic transmission used in the Ford Escape, Ford Fusion, and a number of other vehicles. It was jointly developed by GM/Ford.

its pretty easy man .. after watching this i can make my own car ..

it's amazing to find out that some woman know something about cars (and even more rarely to see them interested on them)

@corvettecentral. HHR. the reason? It is a gm plant

@joelanderson000 Good point...it seems as though the cars themselves are more a mix from different countries than a lot of the people that drive them. It doesn't seem like a single car really lays claim to a single country or heritage. In the end some amazing examples have been created.

this video changed my view on life

nice video though kind of looking for a more detailed video showing the complete production line and how many people are used in the assembly line to build a complete transmission.... by the looks of it ... it seems a group of people are being used that do specific tasks of building components of the transmission... such as a person to put in the plantery gear assembly , a person for the washer, clutch rings,... so on so forth

damn Automatic has so many parts and the way they are setup,

I don't think ANY year was a good year for the Ford Taurus. I have three friends that took their Tauruses to the scrap yard, and a fourth that just plane abandoned it in a small town gas station. Best of luck to you. Times must be tough if your trying to keep a '97 Ford Taurus alive. Godspeed, brave soldier.

i understand everything now XP!!!

i agree with you , to actually think of all this is truly a work of genius...i wonder if they were from MIT.

so you mean its a 1 wheel drive? only the passenger front wheel gets the torque?

@TheGrahamDillon Same here. I get engines, manual transmissions, and even some continuously variable transmissions, but automatics are a mystery to me.

Pretty cool stuff. I'll always prefer my standard though.

On an unrelated note, why not use a single, tapered gear? A non-tapered gear could slide along the tapered one, which would change the gear ratio without the need to release power from the engine, and would provide a theoretical infinite number of gears... The only issue I can see with this is that you would need a rod that can adjust in length so one gear can slide back and forth, but that shouldn't be an issue...

one of the main reasons it cost's so much for overhauls is the liability if it does not work correctly,as they are not always easy to tear apart and figure out "why" they don't work..

@JetMechMA Linux is the 'manual' version of operating systems, while windows is more of an 'automatic' version.

Hi there i love your video thank you for sharing that , i have question for you if you can help me with my car . i have 1968 cadillac devill that i purchased from arizona , in the first day the tranny was shifting smooth then start acting bad ,now when the car cold shift perfect after 2 or 3 minutes driving the tranny will shutdoune notheing go in gear it well go in gear if i tern the car off and restart it and it well drive for a little and stop , if you can help me pleas let me know whats going on if it need a rebuild or not , thank you best regard OMARI

really a manual is quite simple. you have the input shaft driving the cluster shaft. the cluster shaft has many gears on it those gears always contact gears on the main shaft. when you push the shifter into first you move a synchro which was resting on a gear locked to the mainshaft. now the synchro is half on the gear locked to mainshaft and half on the 1st gear. 1st is now enguaged. its the same for the rest except 4th. 4th just locks the input shaft and mainshaft togeather 4th is direct drive

Did you get all that ?
