Hi ,

My BMW X6  Transmission GA8HP75Z had been replaced by  BMW genuine newone, which the part number accodingtly with it.

After programming and coding EGS by ISTA +. All faults code are cleared. No faults present. But the gear shift selector do not respond when changing from P possitsion to N, D, R. and so, the Car cannot run.

 Frankly, I do not know what to do next. What wrongs that I have done ? Can anyone show me ? Thank you very much.

Best regard,



Very sad to hear about your problem mate.

1. We need to start by looking at if you really got a genuine part from a dealer or an import?

2. Did you install it yourself? Was the installation correct?

Also, if your system doesn't show faults doesn't mean there is no fault. Do you have  a professional scanner at home?

What it seems like is a simple problem with the circuit transmission. Even though everything is alright, your transmission is not getting the correct power.
