2019 Ram 1500 Borg Warner Transfer Case
What brand fluid are you using in your BW 48-12 non auto transfer case?
When I look online some suggest that ATF+4 is ok but then all the other fluids seem to be for the BW 48-11 auto transfer case which are $20 to $70 a quart.
Valvoline transfer case lube is also available for $15 a quart .
So what fluid is ok?
thanks

The specification the fluid needs to meet does not change, just the Mopar part number. BorgWarner specifies the same fluid for both the BW 44-44, and BW 44-45.
