Now my daughters truck has a new problem i,ve been trying to fix,.
It started with the P0785 code, so i changed both solenoids, cleared code , ran fine for 2 mins till it got a little warm then cel and limp mode same code.
I then changed the pressure manifold, cleared code, again drove great 1-2-3-4 lockup for 2 mins then code is back.
I can tell its heat related, because sit over night and it'll drive fine for 2 mins. If i clear code and let it idle for 5 mins or more it codes again, when its warm i cannot clear the code.
Has anybody else experienced this? 4l60e's are bloody nuisance.
Thanks for any help Truck is 1997 305 4l60e
