Dexron 3

[bgred2]

What brand Dexron 3 do you use and where do you get it?

[ParadiseMJ]

I used to get whatever brand of Dex III at AutoZone or Kragen. Getting harder to find, I use Dex IIII (or anything labeled Dex III or better) now. I'm not looking for brand, just the Dex (III or IIII).

Dexron III has been replaced by Dexron IV. You can get it anywhere.

Dex 4 is NOT an acceptable fluid for an aw4 found in xj and mj

[maddzz1]

Most stores I see now caryy Merdex or whatever its called. Supposed to be usable in anything that calls for Dex3

Why not? (Said the guy with the 5-speeds)

Dex/Merc (Dex 4) has been the only ATF in my 1990 AW4 slushbox for 4-5 years and about 50K miles. If it's not good for my tranny then I'm screwed. Now ATF+4 is a different story.

That's for Fords.

ATF+4 is for chryslers. At oreillys we sell the valvoline dex/merc which will work for dex III, also our oreillys brand "multipurpose fluid" also is dex III

sorry, I did mean atf + 4.

 

atf + 4 disintegrates all of the brass in the clutch packs.

 

 

I've not heard GOOD things about dex merc IV, either, though. but then again, I haven't heard bad things...I can still dex merc III, so why would I bother buying IV.

 

 

you can get III at bumper to bumper.
