What is a Transfer Case and How Does it Work?

A transfer case is a special gearbox that is typically found in four-wheel drive and all-wheel drive vehicles. Its primary function is to transfer power from the engine to both the front and rear axles of the vehicle. It works by taking power from the transmission and dividing it between the front and rear wheels, allowing all four wheels to receive torque simultaneously.

The transfer case is equipped with a variety of gears and components that allow it to perform its functions effectively. These include a chain drive or driveshaft, a range selector, and various drive modes such as two-wheel drive, four-wheel drive, and low-range gearing for off-road conditions.
