**** Bear with me here, but the transmission was not drained, nor dry.
I checked the fluid level warm after a 20 min break in period on the
engine rebuild and it was ok.

****"tangs lining up" - I think you are talking about internal to
the transmission? The tranny was not stripped down nor taken off the
car. The engine was unbolted from the tranny by the 3 bolts and the
tranny was left in situ on the vehicle.... Maybe I am misunderstanding
this one...

**** I will perform that check a little later on today and see what I
see.
Thanks!

When the trasmission is removed from the engine the converter is
loose, other than hanging on the center shaft. It can be removed by
simply pulling forward on it. The tangs that drive the pump have about
1/4 - 3/8 inch engagement. If the converter moved forward that far and
rotated a very small amount it will not drive the pump until engaged
again. You should have been able to tell that when you tried to bolt
the transmission to the engine block. Sadly that is sometimes over
looked as oft times we are on our backs talking in an unkind manner to
the SOB. Also the bell housing bolts are strong enought to crush fit
the tangs to a non working configuration. BTDT, $^&&*&*%!!
