Differential fluids?

Sorry if I missed it. Does your truck have the "auto 4x4" option or just on/off 4x4 buttons. I always get confused as to the transfer case fluid requirements/recommendations between the two. I thought they were both 44-44s. My plan was to use Maxlife ATF in the TC of my 2019 Ram 1500 classic (w/out auto 4x4). I plan to use maxlife atf in my ZF8 as well when the time comes.

Yes my truck has the 4 x 4 auto button on the dash. After reading some of the opinions here I decided to use the Amsoil mv atf fluid in the TC
