I don't get it..... are you scared of a tranny rebuild? You seem to be real good with almost any other part of truck.. Why not pull apart a tranny and go through it???????.? I can school you how to backyard the whole thing.

You can pull a pump with a couple of bolts and claw hammer. Drums you can use some long welding vise grips or a clamp to get the drum apart...Stop screwing with used junk and freshen up one yourself
