i have a 1996 buick roadmaster wagon, it has a 4l60e trannsmision in it. It lost its reverse gear. i also have a 1993 buick roadmaster wagon in rough shape body wise, but great motor and tranny. i believe it is a 4l60 in the 1993. i know the 1996 has the electronic controlled tranny and the 1993 probably doesnt, so what would i need to do to make the 1993 4l60 tranny work as a replacement for the 1996 4l60e tranny.??
