727 not pumping fluid

Here it is. I have a 727 rblt by local shop using kevlar bands, rev man valve body.
All transmission lines are dry. I took off the forward fluid line and started the car in neutral. No fluid comes out in any gear when running.
I have a new Hughes 4000 stall. Car is on stands and wont turn the tires AT ALL in 1st even at 4k rpm or any gear. This led me to check fluid flow at the lines. I have none. Fluid is full idling in nuetral. I think the fluid not pumping is the problem. What will cause this? I do NOT want to remove trans if at all possible in getting this fixed.
