What kind of oil does the transfer case require?

The type of oil required for a transfer case typically depends on the vehicle's make and model. Many transfer cases use automatic Transmission Fluid (ATF), while others may require specific gear oils, such as 75W-90 or 80W-90. It's essential to consult the owner's manual or manufacturer specifications to ensure the correct oil type is used for optimal performance and protection. Always follow the recommended maintenance schedule for fluid changes.
