The transfer case is found on all-wheel-drive vehicles and is responsible for the front to rear distribution of power. Proper service and fluid changes are required to avoid costly failure. 

VTT now offers the ONLY easy-to-install, plug-and-play xDrive controller on the market. This device will allow you to turn off and on your xDrive capability from the driver's seat with a remote. While other options do exist such as X-Delete, or an in-dash gauge, one is a very slow process and is not viable to use as a way to do a burnout at the drag strip, and the other is a very expensive, AND very intrusive device that requires removal of most of the dash, and installing a gauge. VTT's solution takes 30 seconds to install once you gain access to the underside of the vehicle, and can be removed just as easily.
