I always get confused with these oils, which one is for the gear box, and which one is for the 4WD box? Thanks ...

 

edit: by gear box i thought you meant steering gear box. if you mean transmission, it's Dexron/Mercon III, not ATF. same goes from the transfer case. so both of those i think are wrong for the XJ. someone can correct me if i'm wrong about the t-case, but i'm sure about the tranny fluid.

 

Arab1970,


You should specify what Jeep you have. Is it a Cherokee XJ body?


What year is it?

What transmission you have. Is it an AW4 automatic transmission?

And, what transfer case you have.

 

Well, I am not sure about some questions, but it's a 2001 jeep. I have the Owner's Manual, and here are some pages ..

 

I wouldn't recommend either of those fluids you show.


The AW4 transmission should be serviced with Dexron III/Mercon fluid and the transfer case can use the same fluid. Dexron II was superseded by Dexron III. Do not use straight Mercon.


Deron III/Mercon can be found by many manufacturers, often labeled as DEX/MERC.


Typical brands shown, other brands available:

Thanks so much.
I always use the VIN when I buy parts, I'll see if it will work.

 

Be careful with this, the parts stores/dealer will try and sell you ATF+3 for your transmission. Do not use this stuff. The AW4 functions best on Dexron III/Mercon transmission fluid.

 

Thanks, I will.
