I used a broader Performance 500HP rebuild kit and TCI 2600 stall. Trans shifts great through all gears. I ran the engine for a minute with cooler lines disconnected at trans and have nothing. There is 14qts including pre-filling the converter and also has a +1qt deep pan. My book called for 13.3qt. The check valve and spring in the pump which is infamous for sticking closed have been removed and the chamber drilled out to .343". Pump must be pumping since I have line pressure for shifting. What is the actual procedure for testing line pressure? I have required pressure but no procedure.
