Does it move at all In drive? Is it like it is neutral or does it feel like its bound up?
What comes to mind:
1) You still may have a forward clutch issue, and the low gear is helping you get moving. Low gear is a combination of the front and rear planetary sets, low/reverse band is applied so the low-reverse drum stays stationary to hold the rear planet carrier.
2) or a severely stuck governor, but if that is the case it would/can effect reverse.
I still think the forward (or rear clutch as it is referred to in relation to the placement inside the trans) is still the culprit.
