shifting problems

vegeta · Mar 8, 2009

Last night me and some friends did a little wheeling. Nothing serious but there was alot of mud and a few hill climbs. When we where almost out I noticed my alt wasn't fully charging. Not a big deal, it's got over 200000 miles on it so it's probably time for a new one. When we went to get on the main road I took it out of 4low and started to take off. It had a really hard time pulling out. I don't think it's shifting out of high gear. It's not showing any codes but I haven't had a chance to look at anything else. Anybody got any ideas?

We're going to need a better description of the problem.

When you say, you "don't think it's shifting out of high gear", you mean the transmission or the transfer case? Do you have a stock Jeep automatic? (AW4)? Did you try putting the transmission selector in 1-2? Is it still acting up?

You might have fried your TCU

sorry, yeah it's the aw4 and I'm talkiing about high gear in the tranny. I think it's trying to start out in 3rd or 4th instead of first. I moved it around in the driveway today so I could wash it and it seems okay now. Last night as we were coming out of the woods I put the shifter in 1 and it didn't do anything, it stayed in drive. Up till then when I put it in first, it downshifted and stayed there. This was with the tcase(242) in 4low. Im not sure what I could have done to damage the tcu as I didn't get deep enough to get water inside. Could the problem be the nss? It certaintly got covered in mud. I though my alternator not fully charging might be the problem. I've read that later model xjs are kinda sensitive about charging problems.

Use a voltmeter to see if you are getting 13.5-14Volts when running. Disassemble, clean and reassemble all battery connections and grounds.

Hmmm... definitely not the NSS. Maybe others can chime in with some other ideas.
