My car drives and idles perfectly , however it will not engage gears 4,5 and 6. Smooth changes from 1, 2 and 3 and that's it ! so limited to 35ish mph
Error codes suggesting shift solenoid C , had this changed and refilled twice of fluid but still the same issue . No longer shift solenoid error code
Was advised to swap gearbox but after reading many forums it seems it could be faulty ECU and so im in the process of trying this before either swapping the gearbox or something else more costly
