So a lil while ago, my Trans lost all gears. I have a 2007 Yukon with the 4.8/4L60e So I’ve been searching for a replacement. I considered just replacing the pump. But don’t wanna just throw money at a trans and can get a rebuild. (Trying NOT to rebuild) So before I get to that point I searched all over the web and junk yards for this trans. What years 100% work? I mean bolt up and go. Only 07-09? 07-13? Is this a 13 or 15pin? Purple or green plug? ISS or Non-ISS? 300mm? Can I use old TC? Thanks for all help.
