hey guys! Doing fluid changes on my new cherokee. What type of trans fluid does trans use? Is it Dex/Merc ATF fine? I read Bulletin about ATF +4 But I'm hearing the AW4 does not care for that fluid and will overheat trans.
https://www.napaonline.com/en/p/VCA773636 is this what you guys use? Thanks in advance!

Dex/Merc. Stay away from the ATF+4.

Any DexMerc will do. Don't sweat the brand. WalMart's house brand is fine.

When I changed mine I used ATF+4 because some stupid site listing all the fluid capacities said that's what it took lol.

Thankfully only a couple hundred miles later I found out it should really have Dex/Merc fluid and I drained/refilled again with Valvoline Dex-III/Merc same as you have linked.

After researching what fluid it really calls for and why there is confusion I found out a bunch of political bull is behind the confusion.
End result of plenty of research and common sense says that Dex/Merc is the proper fluid even if ATF-4 does work in many cases.
Plus Dex/Merc is cheaper! 😉

Chrysler dealerships decided to only stock 1 transmission fluid so as to not make mistakes and the XJ was about to be discontinued at that time anyway. That's the story I got from a parts manager I trust. They've also changed their power steering fluid to a different formulation at about the same time.

You got that exactly right!

Plus, the transmission's manufacturer, Asin Warner, has never recommended anything but Dex/Merc.

I find it amusing that the AW4 and other Asian Warner transmissions are used in Toyota trucks, especially the smaller ones the ragheads like to use!

Thanks everyone! Been a nice weekend. Trans fluid changed now nice and pink/red. New LED headlamps installed. Hitch installed, new muffler installed and did a full interior detail and 303 aerospace the interior.
