What fluid type is associated with the transfer case?

The fluid type associated with the transfer case is automatic transmission fluid (ATF). The transfer case is a crucial component in four-wheel and all-wheel drive systems, responsible for distributing power from the transmission to the front and rear axles. ATF is specifically formulated to provide the necessary lubrication, temperature control, and hydraulic pressure needed for the operation of the transfer case.

Using ATF helps in maintaining the fluid’s viscosity and lubricating the gears effectively, ensuring smooth operation and preventing wear and tear on internal components. Moreover, ATF typically contains additives that help resist oxidation and foam, which can be beneficial in high-stress driving conditions.

In contrast, engine oil is primarily used to lubricate the engine itself, gear oil is used in differentials and manual transmissions where higher viscosity is needed, and brake fluid is a hydraulic fluid used in the braking system. Each of these fluids serves a distinct purpose that does not align with the specific requirements of a transfer case.
