Same problem with the old pump? And pump drive off the crankshaft is good, pump is turning?

Expert:  Curtis B. replied 2 months ago.

Only thing I can see that would affect the systems is the pressure control valve, it could be stuck and bypassing the fluid back to the transmission case. See the link above.
