Mechanical Shift Transfer Case

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The transfer case is a Magna Powertrain 2-piece aluminum transfer case design. Vehicles equipped with the 5R110 transmission include an aluminum adapter that fits between the transmission and transfer case assembly. The transfer case transfers engine power from the transmission to the front and rear axles. Under normal driving conditions, the transfer case should be in 2H, but when desired, the operator can shift into 4H or 4L. 4H and 4L modes are intended for use in slippery conditions, such as ice and snow, or in off road situations only. 4H and 4L are not to be used on dry pavement. The MSOS transfer case is shifted manually. The unit is lubricated by a positive displacement fluid pump that channels fluid flow through holes in the mainshaft.
