Anyone know what the deal with this fluid in? Not that I need to change it now, but just wondering what the special fluid is. Of course the Dodge Dealer doesn't have it in stock, and I can't find any info on it at all. This is the Borg Warner 44-44 Torque on Demand transfer case. 4auto, 4Hi,4Low,2wd, Nuetral. Used in the new Ram Trucks.
