Redline MT-90
Meanmax says 10w-30 is fine too

Technically, Redline MT-90 is a 75W-90 which exactly meets the factory spec. MTL is a 70W-80 which is close but still works fine which would probably be fine for cooler climates. I'd rather use MT-90 in a warmer or hot climate.

I just changed my tranny fluid to Redine MTL, this weekend and notice a distinct difference in how it shifts. I still have to pause when shifting to 2nd, but it's not as pronounced and the rest of the gears are very smooth. As an FYI... according to the Redline website, Redline MT-90 is equivalent to 15w40 motor oil and Redline MTL is equivalent to 5W30. 10w30 is what's recommended for the AX15. Meanmax quotes the Mopar specs in the following thread and includes a link to some statements from Jeep engineers that confirm the use of 10W30. Seems like either is fine (according to the Redline webite, both meet viscosity requirements for 10w30), so it's a bit of a pick'em. Some people who switched to MT90 to clear up notchy shifting, report additional improvement when switching to MTL, so if you AX15 shifts rough, you might consider going straight to MTL.

Use some folded aluminum foil to make a "chute" for the fluid to leave the drain hole and travel to your drain pan. That way you won't end up with oil all over your transfer case skid plate, and everything is real clean. Someone else posted that here once, and I used it, worked great and I have used the aluminum foil trick for several other projects since.

When I bought mine it had a real bad shifting problem going into second. Gears would grind and it was very difficult to get it into second. Especially being here in Alaska when it gets real cold. Drained the very chocolate shake looking water contaminated oil and replaced with 10w30 and have been extremely happy witht the result. The synchros freed up and now it shifts like a dream. So if you are wary about putting 10w30 rest assured that it worked very well for me. Bought some redline mt90 but have been so happy with the 10w30 that I have postponed putting the redline in until the late spring fluid change.

I did the same thing, only with a piece of thin sheet metal that I cut and bent up to a shape that worked very well. Not a drop spilled.

Of course, when I did the transfer case the following week, I opted not to drop the skid plate and let it all drain through the holes. (I figured I'd rather clean up that mess vs. deal with spinning nutserts.)

If it's a 75W-90 GL-3 or GL-4 which is what the specs for your transmission call for, that would work fine. If it's not, I wouldn't use it.
