10 Things You Should Know About the 2011 Chevrolet Silverado
#5. Silverado HD Upgraded for 2011
Fans of the Chevrolet Silverado HD might have noticed some changes to the drivetrains listed in the previous section. Better power from the vehicle's turbodiesel engine isn't the only thing that's new about the Silverado HD - the vehicle's Allison transmission also offers a new exhaust brake system that helps to slow down heavily laden trucks without heating up the brake pads.
Trailer sway control and hill start assist are also available on single rear wheel HD models to help improve load stability and reduce wear on driveline components. Rounding out the list of upgrades to the Silverado HD is an auto grade-braking feature that downshifts the transmission while rolling down hill in order to take advantage of engine braking and maintain a steady speed.
