Big surprise, tranny is toast! I have a junkyard ticking timebomb in it right now. 04 envoy 216k miles.
I'm wondering what rebuild kits and modifications people have put in. I wont be doing any hard off reading, maybe the occasional muddy field and seasonal snow, towing is doubtful but I'd like to be able to move a load if I can

I'm going to do an upgraded shift kit, better Tcc, obviously I want to get something with a better sunshell and rear planetary, I looked at the monster kits, but for the price I may as well get one of their trannys

I'm at the point now where I'm going to replace this tranny, I'm thinking of swapping a 4l65 in, does anyone know if that takes any extra effort?

It is the same transmission aside from a few internal factory upgrades.
