Thanks for your information. It seems they changed the oil with the car running, dont know about the temperature. Regarding the parasite I will check that, the car had changed the radio and has two dvds in the headrest and one cable is in the floor disconnected, that might be the cause.

Now a few days later we tested the car after the tranny oil was changed, and the car has almost the same symptoms, but in M mode the car will take all 5 gears without problems, it shifts on time, same with reverse, so Im thinking if it be good to change the transmission solenoid valve and the wiring harness with temperature sensor.

Wednesday comes a mechanic from BMW to check on the tranny see what he says. I just dont want to go and swap the tranny and have the same problem, if you know what i mean.

I dont get faulty codes from the ecu regarding the tranny.
