The 2020 GM HD trucks have available automatic 4WD (high range) mode. This is still a 2-speed transfer case with 2WD, Auto/4WDHi locked, and 4WD Low locked. I have something similar in my Suburban and many many of the half tons have had it for 20 years.
I use 4WD auto when the roads are partially snow covered for improved stability with the ability to turn on pavement without damage and binding.
Where are you guys getting the auto 4 wd from? In mine, 2020 2500 lt gasser there is 4 low, 4 hi and 2 wd. No auto. Unless the 4 hi does both? My old 2012 1500 had 2wd, 4 hi, 4 low and auto. I haven't sceen the auto in the 2020 2500s.
It may be the trim line. Mine has the auto feature along with 2 wd, 4 low, 4 hi. On mine you can turn the tow haul knob to the right and it will put you in off road mode. Some trim lines have off road, wetgrass, snow, mud and other modes. Z71/AT4 for example.
