Okay just to be sure you did make sure you got torque convertor bolted back up properly ? Also did you get a warranty for the rebuilt unit? So you select D and you can actually feel the engagement into D correct then you give it gas and no go just revs.. HMMM I would suspect that if you can feel the engagement then you have some issues here sounds like could be a VB issue but hard to tell because you can feel the engagement but no movement. Got to be pressure getting there to engage but maybe not enough pressure to hold engagement? Did you have to adjust the bands also what about reverse does it rev only in reverse also?
