Do you notice difficulty in your car when changing gears? The transfer case fluid may need to be changed.
All four-wheel and all-wheel drive vehicles have a special gear box called a transfer case that sends drive power from the engine to the front and rear axles. Lubricant fluid in the transfer case helps keep the gears cool and turning smoothly. Changing the fluid at can help premature wear and damage caused by contaminated lubricant. It will also need to be changed if the fluid is dirty or the car can’t change gears.
