From someone that has worked on cars all of my life, this is the first time I actually came to understand what happens inside an automatic transmission. Thanks for the post!
you probably dont care at all but does someone know of a method to log back into an instagram account..? I stupidly lost the password. I would appreciate any tips you can offer me!
@Clayton Francisco I really appreciate your reply. I found the site thru google and I'm in the hacking process now. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
Good catch, I forgot to include it while shooting the video. Reverse is accomplished by applying the C3 and C5 holding clutches and driving the rotating clutch housing with the turbine. The reverse gear ratio is 4.49:1. Reverse can be accomplished even if the transmission is unplugged from the electrical system because the default "normally open" or "normal closed" power off state of all the solenoids allows it to happen.
I like your straight-to-the-point way of explaining.The one thing I still do not visualize, is how the clutch packs break and release the drums of the planetary gears and the clutch housing.
amazing video, you sound more like an academic rather than a random repair shop guy. I admire you, thank you so much for putting time on educating others.
Hi, Good question. No, it would bind up because the C2 clutch turns the P2 ring gear which forces the P2 sun gear to rotate. the P2 and P3 sun gears are connected together with an intermediate shaft. The P2 and P3 gear sets are Simpson style gear sets and are driven by a simple gear set P1. Also, realize that 6th gear is already a double overdrive with a gear ratio of 0.61:1, a 7th gear would be a triple overdrive and could be difficult to utilize.
Thank you very much for helping me in understanding automatic transmissions that have been for my a taboo for many years as a mechanic, and for helping me getting prepared for my ASE test. I will follow your transmission videos.
Hi, the clutch packs can be used to stop a ring gear, a planet carrier, or even a sun gear; it is dependent upon the transmission design. Clutch packs can also cause gear components to rotate under power. Each set of planetary gears can provide two underdrive gear ratios,direct drive, two overdrive gear ratios, and two reverse gear ratios. Typically there are only one useable underdrive, overdrive, and reverse gear ratios though.
i used to make the steel clutch plates & some other transmission parts for G.M. used in this transmission. its nice to see how they are actually used & work together. thanks for the info
Wonderfully demonstrated, most magnificent design thanks be to our brightest minds. Here's to the industrious, brilliant engineers and tool makers who make turning the wheels of commerce possible.
Manual transmissions were simpler and separated the drivers from any idiot who could crawl his way behind a wheel, gone are the days when they tested your metal by putting you in a twin stick or a 2 speed rearend truck. Now any idiot is allowed in the large vehicles and they cost thousands to have fixed and there is no chance of doing it yourself, Easily 5 times as many moving parts inside, oh yea you have very little if any control over what gear you in or when, garbage if you ask me, one of my biggest mistakes was buying an Allison in a truck I depended on
For those who dont know the 6l80e in half ton and 90e in 3/4 ton and up are based exactly off the allison amazing design and stupid reliable if taken care of the 6 speeg gas trans was first introduced in 09 and has proven itself time and time again just like an allison
HI, good question. The C2 clutch turns the P2 carrier and the P3 ring gear as an assembly. The C5 clutch holds the P3 ring gear from rotating. The transmission would lock up if you applied both the C2 and the C5 clutches.
I did get the names mixed up there, sorry for the confusion. There are only 3 planetary gear sets from front to back: P1, P2, P3. There are 5 clutch packs from front to back: C1, C2, C3, C4, C5. C1 and C2 connect power to the planetary gear sets, the C3, C4, and C5 stop parts of the planetary gear sets. C3 stops the P1 ring gear, C4 stops the P2 ring gear, and C5 stops the P3 ring gear. The different combinations of rotating and stopping gear set parts gives us the various gear ratios,
your the last of your kind I don't know how to thank you enough for this information I wish they would have classes or instructors like you today that don't mind teaching younger generations we are loosing skilled people like you hope I could be as good as you when I get older and have more experience thank you sir!
Wow thankyou for the video! Been trying to get my head round how these things work and youve just made it seem really simple! Wish i had this gearbox instead of the 4l60e! Its made me realise how much stress those 3-4 clutch packs were under with your demo!
Great video! It's amazing how mechanically simple this transmission is. No sprags/roller clutches, only 2 clutches and 3 brakes. The older 4 and 5 speed automatics seemed to be packed full of bands, clutches and those terribly unreliable one-way clutches. I suppose the all the complexity has moved from the hardware to the software now, since you can just "program" a smooth shift in software, instead of having to figure out how to do it hydraulically or mechanically.
Hi, there are more differences between the 5 & 6 speed transmissions than the TCM and valve body. There are torque converter, case, clutch pack and piston changes for durability too. True, you can make a 5 speed have 6 speeds, but it is not the same as a true six speed. 6th gear is only a 10% change, hard to justify the cost. To answer your question, don't forget the P1 sun gear is always driven without a clutch by the turbine, this eliminates the potential for additional useable gear ratios.
Good presentation. However one thing that would greatly improve it is if you indicate the actual assemblies that power is flowing through i.e rotating clutch assembly to sun gear of P1, PC of P2 etc. That would really give us the exact picture. Cheers
Great video for power flows i normally do Eaton Fullers and never touched any autos and this was very helpful for my understanding of the clutches and brakes of the planetary gear sets
WOW, that's crazy knowledge. Thank you, We're all better off having heard that detailed explanation. I always wanted to know how the heck they get 2 speed out of a single gear set. One suggestion though, you should try to hook up a slow motor drive to see it turn without having to use your hands. But totally awesome, I'm going to try to make a static display like that one.
Great video, kinda sad tho, I believe I watched a later video 2 from 2013 where this gentleman was in a electric wheelchair. I hope his life is and has always been good
Thanks for showing to us, I would like to understand how torque converter is always full, and from where the atf goes to him? Another doubt is how the axis are made and how many holes are inside there?! Also, how the break bands work? How bell housing is made!?!? Thank you, till next video!!!! Please, Brazil watcher here.
I needed a box of tissues and a couple hundred replays of this video (and 3d animating videos) because studying how an automatic transmission works is scarier than watching a horror film in my eyes; but I'm slowly getting the gist into how an automatic transmission works.
+WeberAuto by the way real quick if you can or have time, How can i change my name From Gabriel "gabriel776" aguilar To something else? Your video actually helped me pass a test i studied it lol.
Thanks for the reply. It's great to have this information at my fingertips. I want to get into some diesel stuff on the side, and this will *definitly* help me at the dealer. Thanks again for the great info!
just a suggestion: you can hang the transmission from a bearing and so that it is vertical and all the shafts are aligned so you do not have such a difficult time with turning in higher gears
You should make a kind of claw handle to help turn the c2 clutch housing....cool video! I haven't seen the auto transmission demonstrated this way before...
Hi John, Thank you for the very informative videos. I've learned so much from watching your videos. I had no idea how an automatic transmission worked before. One thing that I seemed to have missed in all your videos is about clutch packs. I realize that the steel clutch plates stay fixed with the transmission housing and are squeezed together to apply force to the fiber clutch plates to stop a particular planetary gear set(s) from turning (essentially like brake pads on a rotor). The question I have is ... it seems like there isn't a lot of force exerted on these parts? Is that correct? Otherwise the fiber plates would wear very quickly? Essentially the way I think it works is the power is always looking for the path of least resistance through the different planetary gear sets and clutch packs. In other words, the clutch packs are really only stopping the inertia generated by the weight of the spinning planetary gear set and not engine torque (or minimal engine torque). I'm trying to also understand how the Aisin Warner AF40 works with regard to clutch packs. The literature describes the shifting of gears being managed by a sophisticated computer program which oversees a clutch-to-clutch actuation. Gear changes are accomplished by one clutch engaging the instant the clutch from the previous gear disengages so I think that would be different than this Allison as there is no "neutral" between shifts - is that correct?
C Collins Hi, check out my video on planetary gear set operation. ruclips.net/video/5piYEX-jRt4/видео.html I cover all of those topics. Get back with me afterwards if you need to. Thanks for watching!
I'm an old truck/bus mechanic, and this trans reminds me of the OLD MT 40 series. I think it was a three speed with a splitter = 6 speed. Does this trans have its origins in the MT truck and bus trans? I also remember the MT was VERY complicated: like 100 valve body movements from 0 - 60mph. And used brass clutch discs. Lawrence.
Dear professor many thanks to your accurate demonstration and i would like to ask you if you could upload a video about manual trans. of Peugeot ROA as it has main problems in the 1st and 2nd gears or could you guide me how to find its manual as you are an expert .. thanks a lot
Yet another great video from you Mr. Kelly! I really admire Your effort to present quite complex stuff in a manner that is easily understandable. Thanks for another great lecture.
The 5 & 6 speeds use different valve bodies, do they not? What I learned at WyoTech is that the only difference between 5 & 6 speeds is the TCM & Valve Body. I hear it's about $1100 just to purchase the Valve Body. I didn't get to learn the power flow which is why I'm here. Great video helps to understand. Q: If you apply C1 & C5 for 1st & C1/C4 for second, could you split the middle by applying C2/C5? Would this work in all ranges? Seems to me that we have a potential for 12 speeds or more.
If you add a secondary gear unit such as GearVendors Overdrive/Underdrive (planetary-type gear-splitting unit) you would end up with 10 forward + 2 reverse (5-speed) OR 12 forward + 2 reverse (6-speed).
Well done video. What about would happen if you applied the c5 clutch pack after releasing c4 when you were in sixth gear? Would it bind, or would it be another gear?
+WeberAuto Thanks for the video, very well done. Following the shifting pattern through all 6 gears, (C1+C5, C1+C4, C1+C3, C1+C2, C2+C3, C2+C4), what would happen if you were to apply C2 and C5 after 6th gear?
+Cobrajr122 Hi, the transmission would lock up because C2 turns the rear two (P2 and P3) sun gears and C5 stops the read (P3) ring gear. Good question. Thanks for watching!

Wes Sugg Thank you!
Sad thing is the Allison 1000-2400 design came from a design written on a bar napkin after hours
Manual transmissions were simpler and separated the drivers from any idiot who could crawl his way behind a wheel, gone are the days when they tested your metal by putting you in a twin stick or a 2 speed rearend truck. Now any idiot is allowed in the large vehicles and they cost thousands to have fixed and there is no chance of doing it yourself, Easily 5 times as many moving parts inside, oh yea you have very little if any control over what gear you in or when, garbage if you ask me, one of my biggest mistakes was buying an Allison in a truck I depended on
For those who dont know the 6l80e in half ton and 90e in 3/4 ton and up are based exactly off the allison amazing design and stupid reliable if taken care of the 6 speeg gas trans was first introduced in 09 and has proven itself time and time again just like an allison
Very informative! I have to say the planetary automatic transmission box is simpler than manual transmission except for the electronic control.
HI, good question. The C2 clutch turns the P2 carrier and the P3 ring gear as an assembly. The C5 clutch holds the P3 ring gear from rotating. The transmission would lock up if you applied both the C2 and the C5 clutches.
Been looking forever for someone to explain autos in a way can understand. Thank you!
Starting to understand auto boxes more now thanks, but if you the expert gets a little confused there's no hope for the rest of us!
+jezzerouse3 Thank you!
Good explanation! Studying the Allison transmission series in one of my classes right now and this was very helpful.
I did get the names mixed up there, sorry for the confusion. There are only 3 planetary gear sets from front to back: P1, P2, P3. There are 5 clutch packs from front to back: C1, C2, C3, C4, C5.

The different combinations of rotating and stopping gear set parts gives us the various gear ratios,
This is essentially revealing magic - I even see some mechanics saying that. But wow, I’ve actually learned something here.

+American Locomotive Yes, it is a very simple mechanical transmission. Thanks for your feedback!
With it's known reliability, strength and especially the dual overdrive , I would think this transmission would be a great choice for racing.
Explained very well. Definitely better than those animated videos. Thanks for teaching me!

tanks for the video. I didnt understand how different clutches apply in different speeds automatically
Thank you!
Hi, Bands can only stop planetary gear set parts. Bands are not as heavy-duty as clutch packs because they do not have the same surface area.
very knowledgeable instructor...
Thank you greatly for posting this video. It has the potential to help the rest of the car world understand planetary transmissions.
Technology at the tips of the mechanics. Thanks.

Yes, of course they do
Change the fluid and spin-on filter regularly,, don't loose or accidentaly throw away the spin on filter magnet.

Nice! Reminds me of my days in the transmission shop.
You should make a video on turbo and superchargers too!
Thank you for the feedback
Now I just have one question.
How did automatic transmissions work in 1940s-50s America when there was little to no electronics helping them?
very informative video sir... thanks allot.. do you also have manual transmission video?
+Shubh Vegas Thanks!

+Kaktus Jack Thank you very much!
Great information how did it take me 10 years to find this
That is what I want to know ;) Thanks for watching
Very nicel explained. Thanks!🙏
It is important for me. Thanks. But why sun gears is faster than holding C1 clutch ?? when you try to make 5 or 6 gear.
I am sorry, I do not understand the question. In 5th and 6th gears, the C2 clutch is applied which rotates the P2 carrier.
came to brazil for to teacher ,here in brazil no one know about these transmissions
Thanks for the free lesson! This is great!
Very nice video, thanks.
Ether you or I missed the part about reverse?
Wonderful Indonesia 👍🏻
Thank you!
That was very helpful thanks
I watched this video, but did I miss the part about "reverse"? I do not remember hearing that discussed.
Roy Harris Thanks for watching, I did forget to show reverse.
The 5 & 6 speeds use different valve bodies, do they not? What I learned at WyoTech is that the only difference between 5 & 6 speeds is the TCM & Valve Body.

Well done video. What about would happen if you applied the c5 clutch pack after releasing c4 when you were in sixth gear? Would it bind, or would it be another gear?
Thank you! It would seize up and stop rotating. The C5 clutch stops the P3 Ring gear. The C2 clutch rotates the P3 Ring gear.
Okay, I thought that, but wasn't sure. Thanks for the reply
Thanks for posting. Very explainatory!
The 6 speed came into play in the 2004 1/2 LLY
Negative. In the 06 LBZ models.
Double negative.
AMAZING, thank you!!
Thank you
So theoretically, if you applied C2 clutch and C5 clutch, it would give you a 7th gear and crazy(er) overdrive?
Awesome explanation!
Thank you!
Thank you for your great videos
you never covered reverse, and is this transmission similar to the Allison 2000.
I forgot. C2 and C3 are applied in reverse.
In the video, you showed c2 and c3 for 5th gear. My guess in c2, c5 for reverse. It seemed like the only remaining combo.
Great video. Many thanks!!!
Good video thanks!
Thank you!
Good beles you working
+WeberAuto Thanks for the video, very well done.
Following the shifting pattern through all 6 gears, (C1+C5, C1+C4, C1+C3, C1+C2, C2+C3, C2+C4), what would happen if you were to apply C2 and C5 after 6th gear?
+Cobrajr122 Hi, the transmission would lock up because C2 turns the rear two (P2 and P3) sun gears and C5 stops the read (P3) ring gear. Good question. Thanks for watching!
