N54 Auto New Transmission need reflash?
Hi all, just got my n54 auto transmission replaced and the car is currently flashed with xhp stage 3. I noticed it will not go into Sport or Manual mode unless I change gear, and after that it will go back to drive. I no longer have the gear number next to the Drive symbol on the dash either. Does this require a reflash? Any help is appreciated thank you

My understanding is you can still use your XHP General flash license but you will have to buy the transmission flash again. You can reuse the specific transmission flash again only if you had removed it from the old transmission AND the new transmission TCU has the same hardware number. When I upgraded to the newer TCU I just bought the Sutphin flash for my new TCU which is far superior to anything that XHP offers...one idea for you. I was able to use my existing General license to flash the Sutphin tune. I also recoded the transmission to the cars VIN number but I'm not sure if that was necessary in the end.
