I am trying my 1st transmission build. I have a th400 that I am putting a transgo shift kit in. I also have a 4l80e just sitting around. I am trying to find out what parts are interchangeable that would help the 400. The 400 is1973 model and the 4l80e is a 1999, I hope I am not biting off more than I can chew.
interchangeble parts between th400 & 4l80e
