Hoping some of you XJ gurus can help me. New to Cherokees but not to Jeeps. I bought a 99 XJ over a month ago from a Jeep dealership that was a local trade in. 2 owners clean title. 4.0 auto 4x4 with no signs of any leaks, air conditioning worked (which seemed to be rare), only 88k miles and overall very clean and maintained. I test drove it - shifted smooth and tracked straight even at high speeds with very little vibration if any. Get it home and let the girlfriend drive it and notice it sometime doesn't catch immediately when you go from dead stop to accelerate into 1st and will then finally engage after a short delay and mild clunk. It really never did it for me so this confused me. Then I realize I don't use the A/C where as she always wants it on. So after weeks of being dumbfounded I put it all together that the A/C seems to the culprit of the shifting issues. I know the AW4 is an electronic transmission and was curious if the somehow the A/C is pulling on its ability to shift smoothly? I am getting tranny fluid and filter changed tomorrow since previous owner may not have recently to see if this helps. Any other ideas? Or is this just the "Chrysler clunk" in a very random and mild form? It only does it in 1st and seemingly only with air conditioning running. After that it shifts flawlessly. Any thoughts/help/ideas would be greatly appreciated. Thanks guys. ![Beer :beer: :beer:](/styles/nc4x4/xenforo/smilies/beer.gif)
