Yep...know a guy that was towing his large boat with a fairly new then truck with a 700R4 trans, it got so hot the fluid boiled up and out the dipstick tube onto the hot exhaust/cats ignited and the whole truck burned up on the side of the freeway. This happening fairly often is partially where the sealed/locking tranny dipstick came about.
