Hello all, I'm at a loss here and hoping someone has some insight. I have rebuilt this thing from the ring and pinion up. Everything that I could buy new, I did. Get everything together, and my bran new transmission is not working correctly. Upon startup, I have over 330psi pump pressure. After shifting gears a few times, the pressure gets lower and lower till eventually theres only 50 psi on the pump port. Everything in this tranny is new except the valve body, or transmission control valve. Yesterday I found a used control valve that was "a good one" from the guy, put it on, and couldnt even get 100 psi out of it. I'm at a loss without ripping this tranny out and having someone go through it. Anybody have any ideas?
