This is a very old and very common problem,USUALLY THE TRANNY TECH TORQUES THE VALVE BODY BOLTS ONCE.
Drop the pan and check your valve body bolts.
Bet they loosened up, if they did, your going to have to replace the gaskets and re-torque the bolts, 3 TIMES
Personally, the guy that rebuilt it would be getting it back,it totally sucks I know.
The techs are good at re-using parts that look good,especially seals that are not included with a cheap overhaul kit,it how they make money, however, you cannot do this with a AOD.You need the expensive overhaul kit.
