Wow thanks for your knowledge sir

I studied auto mechanics in Fenger HS in Chicago, in 1949, by a VERY knowledge teacher named "Mr Loizo". Truly the greatest teacher I have EVER known. He was a former GM engineer. I am 84 now and it took me this long to find a teacher I could call "second" ONLY to my beloved and late Mr Loizo". Thank you so much for making an old man's day in my waning years. Note: Automatic transmissions were in the VERY infant stages then; and obviously little was able to be taught to HS students. However, we WERE introduced to planetary gears using GM's Hydormatic Transmissions. As I recall, it had 3 sets of PG's. But that is ALL we were shown. But I never lost my craving for more. So I thirsted for more and more in various and sundry places all these ensuing years. But NOTHING helped me like your unprecedented video. I am blown away.... Wow! I understand it now. Wow! I feel like I could run down the road and "eat the bark off of trees". Yippee! May Jesus richly bless you and yours always dear sir. carl dixon

You are correct John. If you know about Fenger HS, you know they had two satellite schools to hold down the load during one's Freshman years. One was called "Burnside HS" (the one I attended) and the other was called Mt Vernon HS. I shall forever be blessed by going to Fenger. For it was one of America's very finest when it came to a true HS education (very rare today). The author of this video reminded me so much of the instructors at Fenger. As a result of the education I received, it helped immeasurably in my 45 yr career in the work place. Auto mechanics I didn't pursue, but NEVER lost my love for it. My career was in electrical and electronic engineering; and my electrical "shop" at Fenger; of course played a major role in that too. Again thanks to this wonderful modern day (rare indeed) instructor John Kelly. If one can't learn from him they can NOT learn. May Jesus bless him and you always dear friend.

Unlike the schools that are built today, they were much more than just a box in years gone by.........thanks again for replying.. I luv Chicago....what a wonderful city... I just took a look on Google Earth. Is Burnside on Langley and Mount Vernon on Morgan St? Mount Vernon looks especially beautiful. I'll have to go take a look this summer when I'm in Chicago seeing my brother....Are these areas considered the far south side? thanks again for replying...JJ

This is the planetary gears in an automotive transmission explanation I've wanted for 30 years. Thank You!

There are people who teach and there are people who have the inherent ability to open the minds of other to allow them to see through the otherwise unknown with clarity.

These videos are extremely helpful. Had I had known about Weber State University before I chose the college I did, I would have made a serious effort to go here. I'm currently in my last semester at Ranken Technical College in ST. Louis, and it has been a terrible waste of money. From the videos of Weber State University, everything here is clean, organized, and labeled. Most importantly the instructor makes a real effort to explain each pieces individual purpose. I don't get any of that at Ranken. Thank you WeberAuto for posting these videos.

You are a legend. I wish you were teaching me. I study automotive engineering and would love to have you as my teacher. The way you explain everything is amazing! You make things sound very simple because you explain things very descriptively and carefully. You go over every question i would ask and made things clear. Thank you for sharing all the content with us!

I've been a car guy my whole life and have understood the workings of most all systems in the car except for the automatic transmission and planetary gear sets. Thank you so much for finally explaining all this in a way I could understand.

It is good to see someone training up the next generation. I made my first repair at age 11 and continued a parallel career in mechanical trades and broadcasting until I decided to go and fly jets. The Allison is a great box. I would like to see their faces when they first look into a Road Ranger, lol.

I searched planetary gear operation as I wanted to see an actual on the bench demo of stopping the ring gears for each gear selection. This is a great demonstration the engineer giving it is a excellent teacher and very patient and thorough!

What a great teacher! Finally I sort of understand how a automatic transmission works! Thanks for the videos for both this and the one about the torque converter.

I have always been pretty mechanical minded, but the workings of the automatic transmission has always been a mystery to me. It is just amazing how simple the principle is and by building multiple clusters, it all works exponentially in its gearing. Brilliant !!!!

An Awsome presentation!!! :) Thanks for it.

Wow an almost 10-year-old video that still keeps on giving. I’m a mathematician and professor, and recently had my automatic transmission blowout. I was uncomfortable with all of the lingo and complicated concepts, and wanted to understand more about the science of how they actually work. I’ve watched lots of videos, but this was exactly what I’ve been looking for. No, I’m not a mechanic, and nobody wants to hire me to work on their transmission, but I do now have both an intellectual as well as a practical understanding of the general basics of how they work now. So thanks!

As a curious layman always befuddled by the planetary gear system in auto-transmissions, let me say, this is the best explanation I've every found. Compliments.

Very good job. Without going into crazy detail you did a very good job of explaining the basics of how the gear system works. Seeing you show the sets actually rotating is worth 1000 words. Breaking a complicated item down into many simple lessons is a great way to teach. If you started going into gear timing and gear ratios it would have been a little overwhelming.

This takes me back to when i was an apprentice 55 years ago,we were sent down to solihul in the midlands to the rover factory for tuition on the Borg Warner auto trans boxes,and the tutor told us always to fit jaguar clutches if possible to obtain them,his reason was because jaguar fitted GM boxes which were the best in the world at that time and the clutches were of top quality materials and therefore the customer would get a good job well done and value for money, We took his advise and continued to do so until i retired with the rest of us.Anyway congratulations i have enjoyed watching and look forward to more of it in the future Regards J.T

***** Even worse is the kind that does this and then starts embarrassing themselves and trying to find fault with you for every little thing they can think of because they really are too stupid to understand what is going on, can't face the fact that they really are that stupid, and try to find any and every fault with the instructor as if that is going to get them the score they desire. They don't even try to mentally apply themselves to what is going on but that is the instructor's fault too in their minds. Usually see this with female students and it is truly pathetic. The male students that do this will try to find fault with the instructor as well and after seeing that there is no hole to run into the endzone with in blaming the instructor for them being natural dumbasses; will then proceed to get private tutors and or resort to cheating but tend to have a little bit more self dignity in front of their peers than their female counterparts. We really need to get back to developing true talent when it comes to science and engineering. If you can understand the simplicity and common sense logic of the scientific thought process after being exposed to every teaching technique possible then good on you. If you can't; then there is no shame in that, it's just not something for you. There are other things you may be good at and should try pursuing.

Actually, I bet she is at or near the top of the class. Yes, she comes across as a bit of a know it all, but sometimes smart people have trouble damping their enthusiasm and not showing off. Plus, I bet as a woman she feels she has to work twice as hard to be accepted and recognized. Of course, in reality this is actually working against her because most of the guys will feel threatened that a woman might know more then they do. Hopefully she will figure this out sooner than later. It's seems like she's busting her ass on this course. She even cited the TSB (Technical Service Bulletin) of another vehicle when they were discussing troubleshooting of the clutch paks toward the end of the video. I thought the instructor handled her very well by letting her ask her questions and answering the ones that would be informative for the whole class, but also ignoring her a bit so maybe she gets the hint to stop interrupting quite so often. Great video, btw! I finally understand how an auto tranny works. Seeing the parts working together really helped me understand this easier.

Break out the 5th wheel comes to mind. Golf at Hill. I must be tired, back to lessons.

Very good explanation of planetary gears. I was trying to explaine them to my daughter and I have a PhD in Physics and one in Engineering and your explanation worked. Mine did Not.
