    Hello everyone and thank you for this great forum, it has been a great help identifying problems in my car and saving lots of money.

    my car is a 2006 VZ commodore (175kw) and is at it again, my mechanic isn't able to find the problem:
    1- gear is stuck in 3d gear (limp mode)
    2- shifting gears manually works perfectly fine
    3- error code on ODBII is: "P0756 - Powertrain - Shift solenoid "B" performance or stuck off"
    the mechanic took apart and tested both solenoids, both working fine
    4- clearing the codes doesn't do anything, they just come back after 2 minutes
    5- disconnected battery for 15 minutes didn't fix the problem

    my mechanic thinks its the TCM but i feel he's just throwing random guesses at this point.
    please help

    You are either not paying him for his time or he should not be your mechanic,
    I think you need to face facts, this is probably going to be a transmission fix that costs a lot of money, maybe even a couple hundred just to diagnose. Go to a transmission specialist is my suggestion.

    ditto - Consult an Auto Transmission Specialist before throwing any more money at it. Good luck.

    If the box shifts fine manually then your fundamentals are okay. Most likely one of two; the PCM is the issue as it controls the solenoid or his test failed to identify a dodgy solenoid. Auto trans specialists will figure this out.

    When the PCM thinks it had a dodgy solenoid it'll go into limp mode

    thanks for all the replies, i took it to 2 transmission specialists and both say it is most probably the Impeller that is damaged, but to be 100% sure they need to take it apart. :( its gonna cost a fortune to fix or replace

    :), $1350 is too much given the total value of the car

    Value of the car doesn't matter, it's a question of the cars value to you.
    Don't forget the car is worth stuff all of it's not running properly so it will cost you whether you fix it or not.

    If you can't afford to fix a car you can't afford to own a car.

    Professional mechanics are not on this forum in numbers. There are mowing their lawn and going on fishing forums.
    Professional Turf managers and fisherman are on this forum playing with engines.

    Sounds like you need a hug.
