I am old school (i'm 82) and I started out with a 1947 chevy fleetline. I broke nearly every thing on it (I was 17) but I did all of my own repairs. It was a great experience. I learned it from my dad, and passed it along to my son. I never really had a conceptual picture of automatic transmissions and torque converters. Your course is fantastic. It makes me want to buy an old automatic transmission and tear it down and rebuild it! Thank you so much! PS, my dad had a 1948 dodge with fluid drive. I kind of understood that, and it was clearly your primitive baseline case.

I've been a truck mechanic for over thirty years working on manual transmissions, Automatic transmissions have always been somewhat of a mystery to me. This explanation has taken all the mystery away. I am amazed at the technology and engineering that goes into developing mechanical systems. Guess that's why it has always been so interesting to me. The "stator" reminds me of a turbocharger, it increases power (torque) with the byproduct of what is already there being used. Genius!!

Professor Kelly, you are one AWESOME and patient teacher and you should be very proud of your work! I've been turning wrenches my entire life but decided that it was time for a change in my mid 30s to get out of the wrenching and management position I had been in for many years and take things to a new level. I was already by then burned out and bored as hell. So I ventured off the beaten path and I've now been a engineer for all sorts of lab equipment used in R&D of new pharmaceutical across a multitude of big down to startup firms and it's much more rewarding as well as a easier way to earn a decent salary and not busting your knuckles everyday in some cases to barely survive and put food on the table. Now I'm older but still turning wrenches on my own stuff being out of the loop for so long in the industry I try to stay on top of current changes in the industry across the board. But out of any other videos I've ever come across so far, professor......yours are simply the best and there's no BSing around and not only the fact that you explain in great depth of the history and theories of how things came to be so, this captivates my attention 100% and I picked up on so many dumb little things I didn't know about or how it came to be which is just as fascinating to me as well! I've probably rebuilt a dozen car and truck automatic transmissions mainly in my drag cars but plenty of other run of the mills domestic GM transmissions over the years. I was missing bits and pieces of how things came to be or how why things were like they were! Like you explained that the secondary hydraulic oil pump on the early Oldsmobile Hydromatics were basically only there for push starting the automobiles of the day which was common place back then. I never knew these little facts because it was never taught by my instructors or was in the books I've read due to relevance and modern designs. I think your an amazing teacher and I love to listen to you talk about these things and it feels like I'm literally back in school while doing so, it's not some greasy guy smoking a cigarette in the garage of his house with transmissions parts and fluid spilled all over the floor trying to explain things, your work is done beyond a professional level of higher learning. The fact you are battling M.D. and are still getting around and giving everything you have to educate the youth puts you upon another level in itself as well as I think most everyone would also have to agree with!!! I WISH they made some good progress in this medicine for M.D. or even better than meds, genetics being it's passed on by the mom at birth. I have a friend who is in a chair now too in his early 40s. We grew up together and he knew that this was his life and basically when it would totally debilitate him, having uncles in his family and seeing how it effected them made him feel pretty bad about his outcome in life. I can fully understand why anyone would feel like that too, it's a definite tough hand you've been dealt! But you've got so much to be proud of! Your accomplishments and services to our youth is something that you can hang your hat on Sir and I honor and thank you for your service to mankind as being a great teacher and seemingly a great mentor to your students as well. That's a pretty rare thing to be able to say you possess both sides of the coin lol but thank you for helping me learn something new as well. Take care and I wish you all the best in your travels, hopefully 🙏 soon they'll have a cure for this M.D.!?!? Sincerely a distant student from NYS Jim C.

An excellent video. You had your students engaged too. I enjoyed the interaction.For a slight update, the torque convertor clutch on a 8HP450E does engage in first gear regularly. When the electronic throttle control is commanded to go to idle the torque convertor lockup clutch is commanded to disengage at the same time. Another thing ZF did with this design is to rethink the damper springs, there are more of them and they appear to be longer. If you covered that in another video I apologize.

Well, thanx for the first six minutes. Don't have to work on these things, I don't do anywhere near that level of work on my cars, but I have seen torque converters, I've asked my mechanic about what goes on, I knew about fluid transfer since I was two, but no one (no video) had simply and at a decent speed disassembled, displayed, shown in context, and reassembled one for an intro tutorial like this one here. So in the first six minutes you did that and it tied all the other shit together. I may have known how the converters worked but I didn't KNOW how they worked. Good job.

Torque converters with the stator in them was around in the early 1960's. British built BW-35 auto transmissions had them. Torque converters with clutches first appeared in some Euro cars in the 1970's. I have worked on these. Early German built cars from the 1960's with auto transmission had a 4 speed box, & this also had TWO internal pumps. The primary pump is engine driven, & the secondary pump is driven by the output shaft. With such transmissions, something very odd takes place. Once the car is travelling above a certain speed, usually around 30mph, the rear pump takes over all internal operations of the transmission, & the engine driven pump circulates the oil through the cooling system. Some British built cars with BW-35 trans of the air cooled type had two pumps, along with some BW transmissions found in some early Toyota Crown cars. A very interesting thing I would like to add is that some Mercedes-Benz cars built between 1959-1965 with manual transmission had an "automatic clutch". These cars had a clutch like a normal car with manual gearbox, but no clutch pedal!! These had a fluid coupling between engine & clutch. The clutch mechanism was operated by a vacuum solenoid with vacuum from the engine, operated by a switch in the gear shift system in the steering column. The release rate was controlled by a valve governed by a control box on the rear axle. The reason early auto transmissions had two pumps is to enable the car to be tow started if the battery was flat, or roll started if you were parked on a hill with your car pointing down hill. My car has two pumps in the transmission.
