Also, the transmission was not COMPLETELY drained, it had just puked some on the driveway, not sure how much.

Also, what I meant is it runs and drives, checks out fine. It makes power. But the power isn't being properly sent to the wheels. It is much weaker than it should be.

The transmission and rear end were fine before, the rear end isn't making any clunking noise or anything like that.. Should I look at the internals of the transmission first? Even though I'm sure the torque converter isn't seated correctly. But it wouldn't move the truck at all if it wasn't seated on the gear would it?

This could still mean that there is trouble in the bands in the tranny. They could be slipping.
