Transmission swap
Got the used transmission from junk yard. My current transmission is 6hp19z,
transmission I bought is 6hp21. Question: Do I just swap TCU/Valvebody and no coding? Or I can I just code it without swapping any hardware? How hard is it to code? Any apps or someone does it remotely? Any suggestions is appreciated 2007 335i e92 |

I thought the 19 was basically the same transmission as the 21? I would just swap the TCU...but if you can figure out how to code it, that would be easier.
