4500 HD/5500 HD/6500 HD works with the available Allison® transmission and the
Tow/Haul mode and auto grade braking features. After adjusting for the load and

system is also included on Colorado and Express models with the available
Duramax® 2.8L Turbo-Diesel 4-cylinder engine and Silverado 1500, Suburban
