Problem with my A-904-A Torqueflight Transmission

Thanks AJ/FORMS for your help.

I have an O.E valve body and I believe the shift kit is a B&M part no. 10226. I did do a hydraulic pressure test on the line pressure port and rear servo apply port. The result was Zero pressure at 1000 rpm and Zero with the throttle lever position moved rearward. I had previously checked reverse gear at 1000 and 2000 rpm result was very little movement. When I first filled the transmission I did notice that the fluid level had dropped and needed to be topped off from the initial fill. Can I assume the pump is working? There are no strange sounds or smells and the fluid is as new. I think the next step is to drop the pan and inspect the valve body and perform an air pressure test.
