42RE new valve body and P1763

death-mobile · 03-03-2009, 05:15 AM

First off...I rebuilt the 42RE from my WJ 30K miles ago. I had APS build the valve body with a transgo shift kit and some other doodads to save me time while I built the trans. The build went smooth but as soon as I put the valve body on I got a P1763 gov pressure sensor voltage input high, but also the sloppy shifts from 1-2 (typical of a bad gov press sensor). I changed the sensor and it fixed the shift problem, however...once I got on the highway and hit a hill...P1763 came on again.

I thought it was the sensor...so I swapped it out. Nothing.

I just changed fluid...adjusted the bands, replaced gov press sensor and solenoid(for the 2nd time)... and STILL...P1763 when on a slight incline for more than a few seconds.

I backed the line pressure spring down to flush...and then turned in 2 1/4 turns. I added a 150ohm resistor to the signal wire AND STILL...P1763 appears.
