    Mitchel On-Demand says Auto-Trak II fluid for the NV case, in the 2500HDs. But the truck is a manual shift case, not a push button... We just switched from AllData to Mitchel(I want to kill management) and I am not sure I trust it. Can anyone tell me which it should have? I will have the truck up in the air in a few minutes to confirm what Tcase is in it.

    a lot of newer ones take Auto-Trak II fluid. I don't think it has to be an auto-trak case to require it.

    Mitchell On-Demand SUCKS! It doesn't list the case this truck has. It has a NV 261. It only lists a 262. I am just puting ATF in the damn thing.

    You will be fine with the ATF. The auto-trac fluid has limited slip stuff in it very much like what you would add to a clutch type limited slip differential. Wouldn't hurt to put it in it either. Just a hell of a lot cheaper to put atf in it vs. the autotrac fluid.

    My 2002 says ATF Dextron III on the case itself.

    I LOVE All-Data. I use it more than I do the Mitsubishi Service Computer. Have you ever used Mitchell? I think its horse**** in comparison to All-Data, and the Labor times are lower :mad:

    in my experience wiring diagrams in All Data are straight out of the factory service manuals. I know they are when it comes to Mitsus and Fords.

    Auto trac is used on transfers with the auto 4WD option. Auto trac is blue in color. Check your fluid, if its red, then its dex III, if it's blue (which I believe only 1/2 tons had auto 4WD) then its auto trac
