Ok, the 4L80E in our 1993 has all but given up the ghost. first reverse and overdrive went, now it has started slipping in Drive. I got a 4L80E that is supposedly good that came out of a 96 or 97 suburban K2500, I plan on rebuilding it and getting a new torque convertor. My question(s) are... any suggestions/pointers towards rebuild kits (brand, etc) we do a fair amount of hauling and towing with this beast, but it is also what has been my daily driver to work (gets better milage than my 92 K1500 suburban with 5.7L gas in it) and my partner has been driving that suburban since it is more reliable. I got a rebuild manual for the transmission that goes through step by step that was recommended to me.
