4-speed automatic transmission

The electronically controlled 4-speed automatic transmission with overdrive comes standard with the Vortec 5.3L V8 SFI engine for control and confidence. It includes Tow/Haul mode, helpful when pulling a heavy trailer or a large load through rolling terrain. Tow/Haul mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control and transmission cooling while trailering. This transmission is standard on 1500 models.
