I have a 97 XJ with about 120k miles on it. I want to get my transmission oil changed or flushed since it has never been. Ive read on here that I should use Dexron III but when I called the guy whos going to change it, he said that they stopped making the Dexron III and now they are using the Dexron IV. Ive only seen one post saying that 4 was bad so i dont know if that is true or not. Has anyone had any problems or experience using Dexron 4?

I haven't heard of Dexron 4. They still make Dexron 3. He may be reffering to ATF +4 but you don't want to use that in the AW4. Only Dexron 2 and up in the AW4!!!

I put Dexron IV in my 2000XJ daily driver 10K miles ago with no ill effects to date.

Dexron IV will have all the properties of Dexron III, and then some. DEXRON III is being phased out, just as you can't find Dexron II anymore.

It shouldn't. I have 10K miles on mine with no problems. Pretty soon Dexron III will be obselete.

ATF+4 is for Chrylser Transmission's only.

I would really stick with Dex III unless it's absolutely not avaliable to you. I don't have anything to base that comment on, but why stray from what the factory recommends?

If your tranny is an AW$ you need to use dex III. The aw4 is buit by toyota,not chrysler.Use dex3 to keep from rebuilding your tranny later on.
