TCM = transmission control module, right? Why would you want to do that? You will need to find out if they used the same transmission. Wasn't the 320i a 6-cyl? They about the same output, so I wouldn't be surprised if BMW used teh same part for both.
I am confused regarding what you expect to gain from this?
