Identification

• The transfer case is located behind the transmission, just in front of the center of the vehicle.
  
  

Function

• After power is transmitted from the engine to the transmission, the power is then channeled through the transfer case, which can send the power to only the rear wheels, or the front and rear wheels simultaneously if four-wheel drive is engaged by the driver.
  
  

Benefits

• In situations where a rear-wheel drive vehicle could get stuck because of the lack of weight on the drive wheels, a transfer case allows the vehicle to pull itself out using the front axle while simultaneously pushing from the rear axle.
  
  

Considerations

• When shifting a transfer case between two- and four-wheel drive modes, be sure to follow your manufacturer's recommendations. Shifting the transfer case at too high of a speed can cause drive-train damage, potentially rendering your vehicle inoperable.
  
  

Warning

• A transfer case is a mechanical device, and in order to stay properly lubricated, regular draining and filling of the transfer case is required. Follow the recommendations stated in your owner's manual.
