Oh and as i mentioned before, he also said they bypassed the pcm and were able to manually command the tc to lock, and that when they did that it did lock. So i would think the tc solenoid is good. Its sounding to me like a wiring issue.

 

He also stated its not throwing any codes

 

"looks good" doesn't mean it's good. And electrical issues can be notoriously hard to diagnose. I'd remove the Edge and see what happens, but I'm certainly not the expert when it comes to electrical troubleshooting.

 

I have no issue removing the edge permanently, like i said i kept it only for the display of temps.

And as far as finding wiring issues i think i could track that down as well, i have an hvac background so testing circuits isnt new to me, neither is knowing how difficult it can be. I just need some direction where to start, once i have the truck back. But even then, how am i gonna know if ive fixed it without some kind of a reader like the AE software. I wont even wanna drive the truck around til i know its right. Dont wanna burn the new trans up.

 

If he only inspected by looking at the wiring, all he did was waste some time. The wiring needs to be checked electrically.

 

Ya i agree, not sure what he meant, but he stated the pcm is sending out the lock signal but the voltage is not making it to the tc. So one would assume they tested that with a meter.

 

Mark i thought of something else. Before i took it into the shop i replaced the front calipers/rotors. The old ones had siezed and overheated BAD, like i looked like steam locomotive when i got it home.

Also, it has an electric brake module, and 2 or 3 different plugs for trailers at the rear bumper.

Could any of the above disrupt the signal from the pcm to the tc in the manner earlier described?

 

The front wheels, no. The electric brakes, yes, if they make the brake lights stay on all the time.

Then that indicates that either the wiring or the solenoid is bad.

 

Ok, i dont believe they are, but anything is possible. Thank you for the response

 

Well issue averted, i finally had time to stop by the shop today to drop some money off to him, he said he worked on it some more and found a bad wire that was grounded out. Stated everything is now working as it should.

 

That would do it! Glad to hear you got it figured out.
