Re: Installed remanufactured trans, but won't move!
I can confirm that what you're guessing is impossible. The pump fills the torque converter. If the engine runs and there is pressure at the test port then the torque converter is filled. If the converter wasn't filled the pump would work until it emptied the pan into the converter, then you'd have no pressure.
