Your transfer case transfers engine power to your vehicle’s front and rear axles. Some transfer cases are lubricated with gear oil, while others use automatic transmission fluid. Transfer case fluid cools and lubricates the gears, chains, bearings, shafts and other parts.
Over time, the fluid deteriorates and doesn’t protect as well and small metal particles can contaminate the fuel, causing the transfer case to wear prematurely. So it’s important to drain it periodically and replace the old fluid with fresh fluid. Of course, it’s also important to use the right fluid for your vehicle, and our qualified technicians can help you choose the right one. Ask your Service Advisor about when you should have a transfer case service.
