I recently rebuilt a 700r4 (first Gm trans I have done) I installed it and adjusted line pressure. When I ran it through the gears it pulled forward in all gears(including Neutral and Park) and would bind in reverse. That seems to me that the forward clutch is staying engaged. I am not a Automatic Pro, but I have several Ford and Chrysler trannys. Any tips that others have ran into?  

Does anyone know which of the 5 holes under the separator plate by the pump are to the front clutch set. The closest to the drivers side is the TCC. But Im not sure which of the other four is FWD Clutch.

The transmission is a '91. Ive checked the ckeckballs and all are correct.  

I went ahead and pulled the trans and found I had the wrong Input Drum in it. I had the old style and its too short.
