It also says that the trans will not function in a production vehicle. BUT, if I read my old TCM file and save it to my laptop, will I be able to write that file to the Supermatic TCM instead of using the interface cable that is included with the new trans?
Has anybody here installed a Chevrolet Performance Parts Supermatic 6L80E transmission in a production vehicle?
Thanks in advance!
