Awesome information Professor! I really like solenoids and electronic control , it makes understanding of control of Auto-transmissions much more easier , than governor assembly - throttle valve used in older transmissions. Мuch obliged for doing these educational videos !
You should be charging money for these videos! Great principles being applied. I have been watching your transmission series trying to prepare for the A2 exam.
@@WeberAuto the pwm solenoids are the ones that control the clutches in zf8hp?? So in the case of zf8hp it has 3states fully open half closed and fully closed and this gives sevral gear ratios for the same planetary gear set? Or is it a smooth transition between open and closed??
Hello professor. thank you for your great educational videos. I have a question about my 2010 ford expedition. When the car comes to a full stop second before stopping sometimes it jerks like a hiccough, and right after stopping it clicks. Sometimes hursh, sometimes soft. Sometimes it only clicks, or it only jerks. It may not do anything for a while, then comes back again on and off. On reverse if I don't wait for a few seconds and push the accelerator pedal, it bangs. Or from almost stopping I accelerate sometimes it will click. Otherwise during the drive all gears shift good. Different technicians told me different things "1.Speed sensor 2.Solenoid 3.TCM update, Flash PCM, ECM, Erase clear the Adaptive tables" so on and so forth. In 2021 I changed the transmission fluid and then again in january 2022 with gasket and filter each time, but nothing changed. If I can have your opinion on this matter I will appreciate. thank you again. God bless.
@@WeberAuto I have to thank you because I repaired automatic transmissions for several years sitting in a wheelchair and if there weren't any personal reasons I would have done this job until today. In the end, I specialized in valve body diagnostics and repairs! I love this technic!
Hi sir, i have a question. I learned a lot from your video's. I have a volvo v70 with an aisin Warner 55-50sn and i was driving normally, no issues before that, and suddenly the gear goes into nutral. DPRN doesnt work anymore and no faultcodes. What could it be?
love this video. would like to get a tool, found it online but it doesn't come with the quick "connect valves??) to connect to shop air. did you just get these separately?
I was planning on that, but they wont let me back in my shop until the COVID-19 Pandemic is over in our area. I am trying to figure out a way to do it from home.
Hi I was wondering if you could please help I am doing a degree in automotive engineering I was wondering if you have any lectures on battery arrangement on how to get range and what the formula for working out power I am doing a major project on electric vehicles if you could help I would really appreciate it thanks
Good to have a proper professional description of the various seals from a qualified engineer. Thank you very much professor, it's much appreciated.
Thank you

I'm hooked on this channel, thanks to you Professor Kelly

Need more RUclipsrs like you!
Thank you
Sir ,
You post videos after a long time . I always wait for your documentation
Thank you
Thank you for this demonstration.
I'd like to see the PWM solenoid in action also. Especially for the lockup converter clutch.
Thank you, it is on my list
Another great video, from a great teacher!
Thanks again! Thanks for watching
This channel is gold, thanks for your work. Any chance of of Twizy EV transmission and battery video ?
@WeberAuto, any chance ? :)
Great teacher - makes concept so clear.... god bless.
Thank you kindly!
I would love to see a more detailed description of how the the PWM solenoids work.
Thanks, it is on my list
Good

@@FirstLast-tx3yj It is a smooth transition between closed and open.

I look forward to a video demonstration of that 10 speed in the background
Thank you, it is coming
You are super in talent teacher love you man❤❤❤
I love this job!
Thank you

Thanks for sharing... Cheers.
Proffesor why do you think they dont use solenoids to open and close the valve train on acombustion engine . Thank you really enjoy your presentations
Thank you. Long-term reliability

It could be a selector issue? What was the problem?
Thanks.
World-class video.
Thank you
also noticed you using clips instead where did you get those
The clips are from the valve body where the solenoids were clipped in place there
I would love to see the solenoids operate electrically on a scope, please.
Thanks very interesting
Thank you
love this video. would like to get a tool, found it online but it doesn't come with the quick "connect valves??) to connect to shop air. did you just get these separately?
Yes, I bought them at Home Depot
Nice video sir
Could you listen for a variation of air pressure to test a PWM solenoid?
I was planning on that, but they wont let me back in my shop until the COVID-19 Pandemic is over in our area. I am trying to figure out a way to do it from home.
Does polarity matter on a pwm/pcs solenoid on a 4l60
My transmission is a 1986 Toyota pick up no identification on the transmission but I gotta stick her on the door and does it show that
Hi I was wondering if you could please help I am doing a degree in automotive engineering I was wondering if you have any lectures on battery arrangement on how to get range and what the formula for working out power I am doing a major project on electric vehicles if you could help I would really appreciate it thanks
Could I use ohm meter to test resistance on the terminal?
Yes, that would check the solenoid coil resistance
SIR I like your channel im from Saudi Arabia we need moor information about 10 speed trans thinks شكرا لك على هذه المعلومات
Thank you. I will provide 10 speed information later this year.
