Question GM1912 Transmission Help

So I completed the three stage intake manifold, and uploaded the accompanying tune, Went fine with the amazon cable, Then later Altenator had overvoltage issues, Then fixed that. After all that decided to do the Trans update for better shifts, figured out after i tried to update it with a crappy cable, and it failed then was unable to go out of park. So I bought new bimmergeeks cable expert, Upload update with that cable and it all goes successful, but still does not go out of park. Any assistance would be appreciated because I'm quite new to uploading batch files and such. (I have a BMW 328xi 2008)

You might be in trouble. You should never use those cheap cables for updating software as they cause problems which you are now suffering from. What fault codes do you have now?
