What to know about the transfer case fluid:

The transfer case is a special gear box found in four-wheel and all-wheel-drive vehicles. It directs drive power from the engine to the front and rear axles. In all-wheel-drive vehicles, the transfer case aids to shift power from one axle to another, depending upon traction situations. Lubricant fluid in the transfer case aids to keep its gears cool and turning smoothly. Changing this fluid at appropriate intervals can help avoid premature wear and damage caused by contaminated or broken-down lubricant.

Importance of this service:

The transfer case is a gear box that is unique to four-wheel drive and all-wheel drive vehicles. The transfer case is in charge of sending power from the engine to both the front and the rear axles, and shifting power from one to the other depending on the conditions of the road. Transfer case fluid is responsible for keeping the components of the transfer case well lubricated. When this fluid leaks out or becomes contaminated, it is no longer able to act as a lubricant, and severe damage can be caused to the transfer case.
