Active transfer case

Easily manage your drive mode to minimize wear and tear and get the traction you need with this active, single-speed transfer case. With a simple twist of a dial, you can switch between 2WD High (to get the best gas mileage in normal, everyday use), Auto (to send power to all 4 wheels automatically only when needed) or 4WD High (to get full-time 4-wheel go-power for off-roading, plowing snow or navigating snowy and icy conditions). Neutral is not included; with this transfer case, your Avalanche® cannot be towed with all 4 wheels on the ground.

This feature requires 4WD models and is not available with heavy-duty trailering equipment.
