Had this exact issue come into my shop about a year ago but on a cobalt, the customer said she had it to 2 different shops before getting a recommendation to bring it to me.
These problems are the ones I like the most, had the issue figured out in about an hour and a half and that’s with pulling the side cover off and verifying that it was in fact a melted solenoid.
Contacted the customer, recommended both solenoids A and B be replaced along with filter and fluid.
Did that, reset the shift adaptations and took it for a drive. Problem solved and I earned a permanent customer

If it were my own car I’d maybe see if I pulled the transmission side cover off and tried to see how much a job it would be to throw a new solenoid in. I’ve heard some are easy to replace. So now if it was someone else’s car I’d be telling them no guarantees at all it’s gonna drive out the door. They still tell me to try it and I’ve been lucky sometimes. Nice job Paul. I like the way you reason stuff out.

I've seen that exact same thing on a HHR. Found the solenoid burnt inside after proving the circuit was intact. This proves why a scope is invaluable at times to see a overall picture. Those side covers are easy to do and I did the HHR one in my driveway. Was a mobile job

Seven hours of searching and watching videos not finding any to vehicle's issue. FINALLY all explained in one video what to do. I am thrilled. So no use of purchasing a new transmission sure has saved my pocket. You may not have part 2 but this one was exactly what is needed. Shoulders feel better already :).

i admit that electricity isn't my strong point but some of the basics that you show on your videos haved saved me money. i was a apprentice train mechanic for PATH . every instructor started his course with the words " remember the basics" .

He seems like a really down to earth guy. I love the way he got excited when the probe maker mentioned him instead patting himself on the back. Good character and smart... very cool. Thanks I'm learning a lot. I'm taking on shift one solenoid problem in my Volvo V70 armed with the knowledge I'm learning here.

It's very interesting to see how other people go about troubleshooting an electrical problem, because as you observe, you gain some great insight on things you can try yourself in the future.

Thanks for walking us through your thought process on all of this!

[otiliohernandez]

I have been in some classes.They only focus on theory but not on how to diagnose like you. You teach how to connect the dots.Thanks for the service you give to the community. God bless your family

[patrickliverpool]

Paul you are a great teacher. I love your teaching skills. I learned a lot from you. I will always be in your class

Great video and explanation of driver and wiring integrity. The Godfather of YouTube automotive diagnostics. Master. 🙌🏽🙌🏽🙌🏽🙌🏽

[david-tjyq]

WOW! You are the man. I have been having issues with my Dodge transmission. I have had my truck in 2 local transmission shops. All they did was show me the codes and said to replace the transmission. Never did any electrical diagnosis on the codes. Seems like most shops see these procedures as a waste of time.

I’ve always watched he’s videos for the last 2 and a half years all over again I’d never get tired of watching him he’s a gift from the almighty god I wish if he was on Netflix to watch he’s video so we can pay him instead of watching those fake movies thanks again you earned my huge respect Mr

Man these modern cars are like robots, my 1966 454 big block Chevy Bel Air never has these modern problems, just get in the car and go every time. And if there ever is any small issue, so easy to find and get sorted. Cool channel guys, God bless from New Zealand.

[gregjones]

Great video brother! Nice way to test that driver and prove the integrity of the wire and pcm!

[labrat]

Thank you for doing these videos "live" as you diagnose and showing that we are also human and make mistakes..Most people diagnose the problem 1st and then post the video with results.I qualified as a technician at Mercedes benz 17 years ago and I am still learning.Thanx S.D.You are awesome bro

[caseyhughes]

You are the only youtube channel that has literally saved my broke ass tons of money. Thanks a lot for what you do.

[jeffcompton]

Merry Christmas buddy. Thank you for all you do. God bless you and your mom and the beautiful family. And of course Mr Pie

[kastooMcFry]

I like that hack by replacing the relay load with some external load so one can pass inspection. Great case study and explanation - Thanks, guys. Loooking forward to seeing how your test light is different.
