The Dodge RAM 1500 Transmission in current production models is a ZF-sourced TorqueFlite 8-speed automatic, designated internally as the 8HP75. This gearbox was developed through a partnership between Chrysler and ZF specifically to balance towing muscle, off-road capability, and highway fuel efficiency within a single robust unit. Select trims pair this transmission with an eTorque mild-hybrid system that adds low-end torque and marginally improves fuel economy without reducing payload ratings. Eight forward gears allow the engine to stay within its most efficient operating range across diverse driving conditions. Fluid changes every 40,000 to 60,000 miles keep the Dodge RAM 1500 Transmission performing reliably, with many well-maintained trucks exceeding 250,000 miles without major gearbox failures.
