Hey all, driving to work this morning after about an 8th mile my 4 speed AT started slipping pretty bad. I eased way off the throttle and put it in first and it stopped slipping, I crawled back home. I called a very reputable AT repair shop, he had a hard time believing me, he said the AT is made by Toyota and should be good for 250,000 miles. He asked me to bring it in and he would take it for a test drive, of course it didn't slip at all on the way or when he drove it. I drove it to work with no problems. After a hard days work I drove home and after an 8th mile it did the same thing, I pulled over and let it warm up and drove home with no slippage. The fluid level is good , is clean with no burnt smell ( had it flushed about 15,000 ago). My XJ has 147,000 miles. Am I in for a rebuild for about two grand or would it be ok to drive after its warmed up?Thanks in advance for your opinions

There has been talk over the last decade or so about the proper transmission fluid for Chrysler products and the problems caused by the improper fluid which in some cases was the "DC approved" fluid.

Do you know what they used at your last service?
Not sure what they used, I'm going to have fluid and filter changed anyway, its worth a shot. That is some good info, thanks
I'm not sure what fluid you should be using other than it doesn't seem to be Dextron even though they appeared to accept it as an alternate years ago (after the ATF + fluids became available
Which transmission do you have? Info on some newer models:

It's the AW4, any ideas why it would only slip when cold? It shifts fine and there is no shudder at all..Thanks
Well, now that we know the actual tranny I dropped back and called 2 people for their knowledge and information.
The parts department at the local Jeep dealership and a local tranny shop (in which I have confidence) both said "Dextron III" for your AW4
If you would have read ALL the information at the link provided you would have known that a I6 XJ uses the AW-4 tranny and it needs DEXRON.

Yes, thank you
Well Fella's chalk this one up to a bad read on the dipstick. When I first looked at it (3 times) it was in the middle of the cross hatched area between H & C, I put in half a quart and it's right at the full mark. No more slippin on cold mornings. Thanks for your input, you guys are great.
