Rebuild transmission troubles

Reread the thread from the beginning, paying attention to those posts pertaining to convertor depth.
-check TC hub and face of pump gear.
-When you separated the TC from the flexplate, did you/were you able to, push the TC backwards into the trans? Or was the TC jammed up against the flexplate?
-If the TC was jammed up, then the pump needs to come out for inspection and probable replacement. At this time verify that the gasket was correctly installed.
-If the TC slid back nicely about 1/2 inch or more, then it may be ok. In which case I would drop the pan and verify that the manual valve is properly engaged with the shift mechanism(rooster comb).
-If the TC and pump are ok, and the manual valve is engaged and you confirm that the TC and trans were working together before the rebuild then; I would drop the valvebody(VB), and confirm the clutchs apply using the air pressure test.
-If the pressure test is no good( pay particular attention to the forward drive clutch), then I would first check all the cast rings on the inputshaft, and the pump gasket, and lastly the lipseals .
-But if the pressure test is good then next I would test the VB. I would be looking for problems in the pressure regulator valve first.
-If you still cant find the problem, you might as well verify that the overrunning clutch(sprag) is assembled correctly.
-What did I miss?
-Oh I know.I hope this is a 1967 or later trans.If it is an earlier unit, they had a checkball in the pressure circuit with a 3/8 ball.Its easy to swap it for the 5/16 ball in the regulator circuit. I have no idea what the outcome of doing that would be as I have never done it. I bet it wouldnt be good tho.
