Autotrac® electronic transfer case

With this electronic transfer case, you have the convenience of Autotrac® (for fuss-free traction as needed) and do-it-yourself control (for choosing the drive mode you want, as conditions demand). A simple twist of a dial shifts the transmission between 2WD High (for maximum efficiency and minimum wear and tear in everyday situations), Auto (for letting sensors determine your traction needs), 4WD High (for extra traction on snow and ice), 4WD Low (for maximum 4-wheel power and extra torque in the toughest situations) and Neutral (for towing your Silverado®).

This feature requires 4WD models.
