Re: 95 Windstar AX4S transmission ATF fluid flow
I had long post written that was lost when I tried to post it (session timed out). It must have been too long.
I don't know why the EPC voltage would increase by adding a resistor in parallel with the EPC circuit. It seems like it should be the opposite (more current, more voltage drop). Can you check it with an oscilloscope (EPC is pulsed)?
You might have a hydraulic leak inside the transmission (e.g. at a pushing passing hydraulic fluid into a clutch pack. When I rebuild my 1996 AX4S, I found several bushings with higher than expected (I couldn't find clearance specs on the bushings). In the same fashion you might have a seal that is leaking.
Have you checked pressure levels directly?
