    Hey guys I’m looking at replacing my transmission in my 1997 GMC Sierra 1500 Z71. I found a fairly new GM crate transmission 4L60E out of a 2004 GMC Suburban Z71 local to me. Would I be able to make that trans work in my 97’ or is there too much difference in the newer 4L60E’s? Thanks!

    Thanks all again for your help. I need the RPO'S decoded to know what calipers and other things. A GMC dealer told me my truck was an HD but no badges. Maybe someone can help me with this. Thanks. I attached a picture of my RPO's. Respectfully, Michael Hogan
