Nope, it is in very good shape. I only had it in a vehicle for one day, and I drove from Eugene to portland, then about 50 miles west of portland towing a pretty heavy trailer with a YJ... then all the way back with a full-size chevy and two engines in the bed of the truck. I had absolutely no problems and it shifted perfectly and never over-heated or anything.
The truck it was in was built just to tow, so this transmission is definatly strong! It was never taken off road or anything either. It's a littly dirty right now, but I think i'll go clean it up this afternoon or tomorrow. Let me know if your still interrested in seeing it.
