I have a 2002 WJ 4.7 with Quadra-trac II (NV247) and am changing all my fluids...
I am finding mixed messages on the internet as to what fluid to use...
The original owners manuals online say to use AT4+ but I have found the following statement a few times, without offering a replacement fluid...
"The NV247 transfer case is generally reliable, but unfortunately does have occasional issues with the progressive coupler used in 4 All-Time. Most service documentation lists ATF+4 as the correct fluid for it, but this is incorrect and Chrysler published a TSB about it in 2000. ATF+4 will cause premature wear and binding in the transfer case and will eventually cause destruction of the case. If the coupler fails, then the vehicle will be in RWD mode unless you engage 4 LO."
This one was taken from

So does anyone know for absolute certainty which fluid I SHOULD be using? It seems to be the only one I cant get a straight answer for....
