What did I do wrong? FIXED IT!!

I just finished putting my 727 tranny back in the Demon. It will not go into any forward gear.

Here is what I did. I took the tranny out to replace a noisy pump and front seal. Other than that the tranny worked fine in all gears. When I replaced the front seal I also installed my other converter as the old one had a couple of grooves on the sealing shaft. When I installed the pump I had the front band backed off and I adjusted it to 72 inch pounds then backed it off 2 turns and locked it down. I will say that I just remembered the tranny was in the neutral position when I did this if that makes any difference.

The tranny goes into reverse perfectly and moves the car with no problems, so I don't think it is a converter problem. The tranny makes a whistling noise at all times now that it never made before. The B&M shifter is moving the shifting arm on the tranny properly. The only things I can think of is I adjusted the band wrong or the pump is in the wrong position by 180 degrees. Unlikely but possible, I have seen stranger things.

Anybody got any ideas and how to check for them? Help please!
