GMC/Chevrolet 2500HD/3500HD Trucks

The extension of General Motors' inside-out pickup redesign brings a smooth-shifting six-speed Hydra-matic transmission to GMC and Chevrolet 3/4 and one-ton trucks. A manual transmission mode gives you control of shifts up and down through the gears. The tow-haul mode holds each gear longer during acceleration, and down-shifts automatically to second gear during braking. The standard engine is GM's 6-liter 353-horsepower Vortec 6000 V8.
