Transfer case service
A transfer case distributes power between the front and rear axles in four-wheel-drive and many all-wheel-drive vehicles. Its internal components depend on correctly specified fluid for lubrication as the drivetrain routes power to the wheels.
Selecting the correct fluid
Fluid requirements vary by transfer-case design. Mobil lists certain applications for ATF+4 transmission fluid and others for its synthetic gear lubricant, where those specifications are required. The correct product depends on the particular unit and its manufacturer’s requirements.
We use the compatible Mobil ATF or Mobil gear oil specified for your vehicle. Properly matched fluid helps protect against wear, heat, oxidation, and corrosion. Temperature and viscosity stability help support lubrication from cold startup through normal driving.
Planning drivetrain maintenance
Consider transfer-case maintenance alongside transmission and differential service. Each component has its own fluid requirements and schedule, so service on one does not automatically cover the others. Review the owner’s manual and service records to identify which fluids need attention.
Recommended service interval
Our typical service reference is 30,000–50,000 miles, with manufacturer instructions determining your vehicle’s interval. Tell our team how you use your four-wheel-drive or all-wheel-drive system and when it was last serviced. That information helps plan maintenance and select a compatible Mobil fluid.
