Problem with my A-904-A Torqueflight Transmission

Today I tried to Tee off the transmission cooler return line and check for pressure, the result was zero. Then removed the supply line to the cooler at the radiator to check for flow and the result was also zero. I assume I have pump failure or improper engagement of the torque converter with the pump. It was so long ago that the torque converter was installed that I cannot recall too much about the installation.
