I got the 454/TH400 pulled the other day and split them apart. I guess when they rebuild the transmission they also put a new Torque convert on it. It was a pain trying to get that thing out, if I tried to lift it above the motor mounts it would hit the hydro brakes but we finally got it out of there.
Pictures!
Now its time to clean up and move some stuff around so that I can pull the cab off.
