6-speed automatic transmission

  • Tow/Haul mode raises transmission upshift points to provide more power to accelerate with a trailer or heavy load and raises downshift points to use engine compression to help slow the truck instead of merely braking
  • Powertrain Grade Braking automatically uses the engine and transmission to slow the truck to maintain desired speeds when driving downhill which helps reduces brake wear and increases vehicle control
  • Cruise Grade Braking downshifts automatically to slow the truck as it drives downhill if it exceeds the cruise set speed by a certain amount
