Default Auto trans fluid confusion

I have to change the fluid in my AW4 auto.

My jeep is a 98 SE with 4wd, np231 tcase.

After searching and reading numerous posts on this and other jeep sites I am completely confused on what fluid to use.

Some use ATF4 and some Dex/Merc3. I noticed many guys have had trouble with ATF4.

In a 98 what fluid is best to use? My jeep has 205+ k on it and runs great right now, but with winter coming its time to change the filter and fluid.

I also see that the same fluid is used in the tcase, what fluid are you guys running in your 97+ AW4's?

On the trani. plug its stamped D2 but that is not available so D3 is correct not ATF4 the AW4 is not a Chrysler trani.
