fresh 904 rebuild, not shifting at all

It does have a deep pan with a deep pan pick up that came with the pan. I beleive it was a mopar performance one. I also did remove a coooling line and didnt get anything but a drip age coming out. The filter was clean last night and it was replaced when it was rebuilt this month. I also proably had at the most added about 6.5 qts at one time with no results as well. I was thinking as well about a blocked passage because so far there is no real observed faults with the pump. Is that common at all and where might a gasket be installed wrong?
