What fluid do i use???

I have a AW4 transmission and I know that takes dex/merc but what fluid would I use in my np249 transfer case?? I had several people tell to use ATF+4 and a few tell me to use dex/merc. What fluid would be the best to use???

ATF+4 in the case. I've heard some people use Lucas.

You could use motor oil in the case if it's thin enough.
