1978 ford f150 put new motor in now tranny won't move no pressure in lines to radiator did I damage front pump in C6 tranny?
When you pulled your torque converter, did you remove the flex plate (some call it the flywheel, but that term is only correct for vehicles with a clutch.) I ask this because the Ford C-6 and the Ford AOD shared very similar design, especially when it came to the design and function of the front pump/torque converter and flex plate. The problem that is constantly found here is that someone unfamiliar with the flexplate on these transmissions reinstalls the flexplate, but with the wrong side facing forward. What this does is it forces the torque converter back a very small distance further and right into the front pump seal. In turn, this causes the seal to heat up and once the bearing race gets hot enough, that's the end of your front pump. This problem occurs after installing the flexplate in the wrong direction, finish bolting it all up and you try to test drive it. You first notice it is slow to shift, but after driving it for a few minutes, or running it while on jackstands, the transmission will give out completely. Even seasoned transmission guys have problems with this issue if they aren't being careful about what they are doing. I hope this helps you.
