fresh 904 rebuild, not shifting at all

rebuilt my transmission recently and finally after a reinstall and getting it back to the point to run, i had no engagement of gears. I had a friend who profeesionally build transmiisions help and i kept checking the fluid and it seemed to be good but only took 5 quarts after a recent rebuild. Im think that it should take around 7-8. The converter has 1 quart put into it and its a Hugh's performance torque converter (2000-2200 stall). The transmission shift level seemed to go into each gear OK (PRND21) but wouldnt engage any ideas?

Trans is a 1969 904 out of a 69 charger
