Hi all, I'm a returning member but I couldn't remember my old screenname or password, it's been too long!
I have a 1996 ZJ, 4.0, 42re. My issue is the two error codes my jeep is spitting out, P1757 and P1762. My Jeep had been starting to act like it goes into neutral when it tries to shift from 2nd to 3rd, and I figured from research that meant I'd be doing a governor pressure sensor and solenoid swap soon, but it came a little faster than I thought. About a week ago on my way home, it decided it would not shift out of 1st gear. I was closed to home and limped it there nice and slow in 1st, low RPMs. I wound up replacing the solenoid and sensor, fresh fluid and filter, full PCM reset with successful clearing of error codes.. Test drove tonight and at first all seemed excellent, shifted from 1 to 2 a bit early (I had played with TV cable adjustment) and went through overdrive fine. Shut it off at a stop on the road and started it back up, wouldn't shift out of first again. Then I shifted from reverse to drive and it started off in 3rd gear, limp mode. So if I shift into drive while rolling slowly in reverse, it goes into limp mode. If i start with the jeep off and go straight to Drive, I only have 1st gear. WTF?! I'm at a loss, anyone have any suggestions? it's capable of hitting all gears, but won't shift through them properly, with new sensor, solenoid, and proper fluid level.
