    Question 95 deville concours shift problem

    This is a family members car, not my own. Car was having a hard shift issue from p-r-d and a bit of a stumble 1-4 gears. It does not feel like slip but a more than firm shift. Tranny was changed but issues were still there. Now I have read that it could be the ECM, just wanna weigh all possible things. I also saw there is a garage shift adapt reset that i'm 95% sure that the mechanic did not do. Is this worth a shot trying first before anything? If so what is the procedure for doing this? Also I did pull up a few codes from the display. Any help would be appreciated.

    P076 Transmission Pressure Solenoid
    S030 Speed Sensitive Steering fault
    S038 Electronic level control exhaust valve short to ground open
    S061 Right front position sensor fault

    I've heard that those rarely go bad, that it might be the ecm. Also I find it strange that it would have the same problem before and after a transmission rebuild.

    Probably true.

    Was that sensor changed in the rebuild? DTC's are usually pretty accurate and hard to deny.

    Honestly I don't know and I know for a fact my uncle doesn't know.. I was just trying to look at other options other than pulling the tranny to change the solenoid. Correct me if I'm wrong but you can't just get to it by dropping the pan.

    Not if it's the one I'm thinking of at the 12:00 position in the diagram above. That one's in the side cover and it's damn near impossible to remove with the engine in the car.
