Question about Transmission & Drivetrain for Pontiac Grand Prix
07 Pontiac GP with 170k miles, transmission recently rebuilt by reputable shop. Keep getting p0741 code (tcc stuck on/off cant remember) The shop has worked on the car 4 times including the original rebuild and supposedly changed all solenoids, checked all trans wiring, including putting in a new wiring harness and I got the car back yesterday with the same code. Drove the car, and it did fine for a couple miles, stopped and car immediately stalled. It did this 5 more times in less than a mile. Got it home and it does it every time it is put in drive, unless you two feet it & hold gas & brake at the same time. Now the tranny shop says (by phone) it is probably the PCM/TCM not sure which or if the TCM is part of the PCM. I know this will have to be programmed by a dealer. Can this be the problem or something else possibly overlooked this many times? Note - every time I got the car back in the past, the code is present but the car has drove & shifted mostly good for about a month at a time, then slips very bad, I take it back, he has said 2nd gear has been "burned up" at least two times. This has been going on at least 6 months now and I am at the end of my rope with this thing.
