Autotrac® 4x4 active transfer case

When you want to take the high road, 4x4 Tahoe® models can help you get there from here. Engage automatic Autotrac® 4x4 mode and the system will detect wheel slippage, transferring torque to the front wheels for enhanced traction. As conditions warrant, Tahoe will return to 2-wheel drive. Manually engage 4x4 on a full-time basis when you need it most.

This feature requires a 3.08 rear axle ratio. It is not available on 2WD models or with the Heavy-Duty Trailering Package. With this transfercase the vehicle will not have a neutral position for dinghy towing.
