Are you saying that the car does not move with the shifter in [D3] or [D4]/[OD] but does move in [D1] and [D2]?
If Yes, then the forward sprag was installed upside down.

Or are you saying the car will start fine in [D4]/[OD] but will not shift into 3rd or 4th gear?
If Yes, then you have a major leak in the 3/4 clutch circuit. Did you air test the input drum both by itself and installed into the pump?
