Title: Correct/Best ATF fot AW4 auto box in 1994 XJ
Post by: LairdScooby on June 14, 2015, 01:41:50 AM: Hi All,

some of you may have noticed from my modified "New Jeep Owner in Waiting" thread that i have now bagged myself a '94 XJ Cherokee 4.0 auto.

Driving home (from Portsmouth to Lakenheath) the box performed as it should but it recently had some work done on the gearbox and/or transfer box and the ATF was topped up with 2L of unspecified fluid.
Being the fussy git that i am, i like to change all fluids fairly soon after getting a new car but so far haven't found anything that tells me the correct or best ATF to use.
Currently i use this stuff in my other cars :

Any good for my Jeep or should i go for Dexron II instead?

Thanks in advance!

Post by: LairdScooby on June 14, 2015, 11:53:44 AM: Thanks - i thought it might be Dexron of some description. I'll also check on the tubs of the Carlube ATF-U that i have to see if it's Mercon ATF+4 compatible as a bit of digging i did last night brought up Mercon ATF+4 as a recommended fluid. Would make my life cheaper and easier if so as i use it in my Rovers as well.
It's slightly different to Dex III so may or may not be - i'll report back whichever way and if i use it for a part change will report on that too.

Post by: LairdScooby on June 14, 2015, 06:00:13 PM: Thanks Mike - that saves me exhuming one of my Carlube ATF-U tubs from the shed to see if it is similar to ATF+4 - Dex III it will be!!!

On a similar subject, i've come across a few references to NOT using Dex II in the PAS on these - can you shed any light on an alternative to the Chrysler/Jeep/Mopar fluid please?

Thanks James.

That's a very definite bit of advice! Any particular reason for being so definite? Also i've seen somewhere on here about a "Thank you" button to thank people who have given good/helpful advice but can't seem to find it? Any clues where it is please?

Post by: JamesH on June 15, 2015, 10:12:44 AM: It is a clear fluid and others will froth / foam and degrade seals used in the system. It's not particularly expensive so not worth messing around with trying to use stuff that is not the recommended fluid.

Post by: LairdScooby on June 17, 2015, 09:23:35 AM: That's interesting to know! Sort of used to things like that as the auto box in my other cars uses a strange kind of adhesive to bond the friction linings to the clutch and brake bands so certain ATFs are a no-no for it. To be honest that was what precipitated the question in the first place.
