Many modern cars include an all-wheel drive or four-wheel drive system. These systems rely on a variety of mechanical parts to operate. One such component is the transfer fluid case.
A transfer fluid case is a device used to connect the transmission system in four-wheel drive and all-wheel drive vehicles. Other common names for a transfer fluid case include transfer case and transfer box.
The transfer fluid case attaches the transmission system to a vehicle’s front and rear axles via drive shafts, or mechanical shafts that enable rotation and transmit torque, or the force of motion, to other connected components. The transfer fluid case distributes the power it receives from the driveshaft evenly between the axles, enabling the four wheels on the car to receive simultaneous torque.
Transfer case fluid typically takes the form of synthetic or traditional gear oil. This oil removes heat and lubricates the internal parts in the transfer case.
