A Guide to the NV 246 Transfer Case

This transfer case is one of the so-called “automatic transfer cases,” or “active transfer cases.” This description results from the fact that the 246 has an “automatic 4WD function,” a 2WD position, a 4WD High function, neutral and 4WD Low position. Driving the vehicle in 2WD has all torque flowing through the transfer case to the rear driveshaft, and the vehicle operates just like a 2WD vehicle.
