Looking at doing a motor and transmission from a 1999 suburban using a 411 ecm into my 72 GMC pickup. My question is if the transmission section of the file for a 2002 express van works for the 99 4L60E? I have looked for and can find bin files for a suburban but those files do not list the xdf to use in tuner pro so I could view the transmission settings. If anyone has a bin and xdf for a L31 4L60E Sububan 4x4 I would like to get those files as well. Any other pointers for a newbie?
