Ive got a 99 80e with 57k miles on it. I replaced it because I thought somthing was wrong with it but new tranny did same thing. (stalled engine when stopped due to tq converter locking up at wrong time because tranny cooler was clogged, got fluid pretty warm but never buried tranny gauge or anything, fluid didnt smell burnt, Im sure it isnt hurt) its out of the truck in my sig, 4wd. I was going to keep it as a good spare but... wanna do some trading? P.S. This tranny only ever saw a bone stock 6.0, did all mods after installing new trans.
