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.
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.
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.
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.
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.
@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.
@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.
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?
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 !
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.
@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
@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!
Bring on the electric car revolution. One motor, one planetary reduction gearbox, and one battery pack. No gear changes, no clutches, no stick shifting :)
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.
This is a Canadian show. taken from wiki "a different voice-over track is recorded for U.S. audiences by Brooks T. Moore (Seasons 1-8, 2001-2007, 2008-present) or Zac Fine (2007-2008)." and " In the UK, rest of Europe and S.E. Asia, the series is narrated by Tony Hirst " So I am assuming this is the Canadian version and not one of the other English versions.
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.
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.
@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..
@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.
@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.
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"
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!!
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.
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...
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.
@TheGrahamDillon Same here. I get engines, manual transmissions, and even some continuously variable transmissions, but automatics are a mystery to me.
holy fucking confusingness!! thats amazing! I had no idea that a automatic transmission had so many parts, gives me more respect for the inverter of that thing, dispite that I drive manual
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...
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.
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.
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.
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 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.
im guessing this is a newer style CVT (continuously variable transmission)?? in witch instead of "shifting gears" you actually shift to different clutch packs that have different gearing in the planetary gears. hydraulic seamless "shifting" with no "shift shock" it drive like it has one long gear like a moped scooter or a snowmobile. even though they show a chevy HHR at the end of the clip im pretty sure this gearbox is not from a GM. honda toyota nissan and subaru use them.
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
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..
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
@ineurodreams i didnt see the original comment but today Lamborguini and Bugatti are both owned by VW and the cars are designed in Germany. they may be assembled in France and Italy but thats about it. so although Bugatti and lamborghini arent German, you could argue that the Gallardo and the Veyron are in fact both German cars. Cheers.
This is another reason why I prefer manual transmissions. I actually understand how they work. Whenever I set out to learn how an automatic works, it's all a bunch of gibberish. The fact that they managed to figure out how to do this shit in the '50s with the old Torqueflite (the first automatic transmission that was worth a damn) still amazes me.
@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.
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
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
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”
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.
Great informative video. Excellent video. Regards,
Suddenly all the GM transmission problems make sense; just look at the amount of fucks not given during assembly.
lol
Not one part pre-lubed!
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.
Transmissions don't last long, but their blocks sure do last forever. 1979 El Camino, original 305. Still going strong.
I was lost after "the transmission in your car......" lol and i was so willing to learn!
Its good, i feel i learned a lot especially from my drivetrain class. I graduate june 09.
This video has just reminded me why I drive a manual... :)
Every time I watch videos on automatic transmissions I want to put a manual transmission into my car.
After watching this 10 times.... I now understand.
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....
WOWWWW, GREAT VID, I HAVE TO HAVE MY TRANS RE-BUILT!!! :-(
Nice explanation about automatic transmission.

Mathieu Thomas Welcome to the real world
I have a diesel car for every day driving and a v8 corvette c3 fuck polar bear and electric cars
Brilliant
ther eis no way that in my life i will owned an electric car i drove a leaf few weeks ago its is awful
Damn I had no idea transmissions were so complicated. The level of complexity in a transmission is insane.
That is actually GMs 4T45e trans.
The vehicle at the end is a chevy HHR
@soco13466 - ah the Kanuten Valve mmm that explains a lot. Thanx
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.

So I am assuming this is the Canadian version and not one of the other English versions.
04:31 they show haw a faulty screw is being put into an automatic gear shift, nice
Mario Josipović Wobbly but is it faulty? How do you know?
looks faulty to me, every part in there needs to be precise, i doubt a wobbly screw goes in there
It is just holding something in place. It doesn't need to be precise.
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.

I worked there for 31 years and started when we built the TH-350 then the 3T40.
I make those plates at 2:30 its kinda cool to see how there used.
@fenixans
Is a 4T60E chevy one
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.
@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..
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
@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.
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

I abslutely loved it.
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!!
that went right over my head.

what they show in the beginning of the vid is a transmission but, aren't they building a trans-axle?
Hats off to the engineers :)
Holy S&@;! That's complicated, it definitely a sophisticated piece of machinery
@APontiacof455cubes
is towing max capacity only for the tranny not the chassis and engine, like the 4l80e has more
@yvesttt the number one car in gas mileage is the Chevy Cruz Eco actually. 42mpg
@0123Brock it is not HP accounts for the real power. Torque is the stress on parts that should be accounted for true measure
Now I know how it's made ! :D
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.

@JetMechMA
Linux is the 'manual' version of operating systems, while windows is more of an 'automatic' version.
@corvettecentral. HHR.
the reason? It is a gm plant
@liltstan the auto will be useful if you are driving from newyork to washinton
@highdeserthater C6 was a ford line of transmissions. You're probably thinking of the muncie 3 speed. just fyi
holy fucking confusingness!! thats amazing! I had no idea that a automatic transmission had so many parts, gives me more respect for the inverter of that thing, dispite that I drive manual

its pretty easy man .. after watching this i can make my own car ..
You haven't bought a dual mass flywheel & clutch assy lately, have you?
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.
how are some auto transmissions able to shift gears faster?
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.
it's amazing to find out that some woman know something about cars (and even more rarely to see them interested on them)
@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 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.

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.
Wow lol.
That sounds fun though. It's a great field to get into. I love cars. So how is it? Did you graduate?
@truenolz
maybe some of us can't afford manual cars. ever think of that?
so you mean its a 1 wheel drive? only the passenger front wheel gets the torque?
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.
@gtuabc I could tell it was gm because of the bellhousing bolt pattern
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.
im guessing this is a newer style CVT (continuously variable transmission)?? in witch instead of "shifting gears" you actually shift to different clutch packs that have different gearing in the planetary gears. hydraulic seamless "shifting" with no "shift shock" it drive like it has one long gear like a moped scooter or a snowmobile.
even though they show a chevy HHR at the end of the clip im pretty sure this gearbox is not from a GM.
honda toyota nissan and subaru use them.
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
Hey, I made these transmissions. In fact, this was shot at the plant I worked at.
Ok that's a Chevy 4L60E transmission. How do you build a reliable one?
Did you get all that ?
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..
@yvesttt so what if they use more gas? they are bigger and have more power :)
@Tommyinoz1971 Manual transmissions aren't "stronger," there are just more parts that can break.
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
@ineurodreams i didnt see the original comment but today Lamborguini and Bugatti are both owned by VW and the cars are designed in Germany. they may be assembled in France and Italy but thats about it. so although Bugatti and lamborghini arent German, you could argue that the Gallardo and the Veyron are in fact both German cars.
Cheers.
Everyone should watch. See how fragile a transmission is. Drive easy, make it last!
Or don't buy a GM. :)
Scott Bates am lookng for type of oil transmission for mazda attenza
what do the fast cars use at the dragstrip?
this video changed my view on life
i agree with you , to actually think of all this is truly a work of genius...i wonder if they were from MIT.
This is another reason why I prefer manual transmissions. I actually understand how they work. Whenever I set out to learn how an automatic works, it's all a bunch of gibberish. The fact that they managed to figure out how to do this shit in the '50s with the old Torqueflite (the first automatic transmission that was worth a damn) still amazes me.
@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.
Pretty cool stuff. I'll always prefer my standard though.
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
Best tran's video on youtube!!!!!!!!!!!!!!
