Hello all, and thanks for the help in advance.
I've recently picked up a '92 XJ. 4.0, 4x4. It had been sitting for three years, and is quite the project - already spent more on it than I paid for it.
When I first got it, it didn't want to shift, at all. Replaced trans filter, did a fluid change. Eventually replaced the TPS, and it started shifting.
Then it started not shifting when first started up (morning or afternoon). If I just drive it, let it rev up to 3,000 rpm or so, then let off the gas and get back on it again, it will shift. Usually after this it will shift fine; sometimes it takes a couple of tries, but no more than two. From then on it's fine until it cools down again. I did a bunch of research, found out the TPS could be the culprit. Tested it, and it seems OK. Replaced it anyway. It still does it.
Any ideas on what to check next? Just as an aside, with a 3" lift and 31's it's getting 13.4 to 14mpg with mixed (mostly highway) driving. I don't know if that's related, but it's just more information. I'll take suggestions on how to improve that, too!
Thanks!
