From 1989 onward, the Cummins B Series inline 6 turbo diesel has powered heavy duty Ram pickup trucks. Dodge was the leader in bringing a light-duty diesel engine to the domestic full-size truck market starting with the legendary 5.9L 12 valve. This engine gained a reputation for its reliability and ability to go hundreds of thousands of miles without major repair. Since then, Cummins and Dodge have produced increasingly powerful work trucks, with modern 6.7 Cummins engines producing 1000 ft-lbs. of torque.
While Cummins engines are bulletproof, the transmissions behind them? Not so much. The transmissions used in Dodge’s diesel applications are not designed to sustainably withstand the abuse of a work truck.
From the early 518 up through the 68rfe installed behind the 6.7 liter Cummins, we are your experts in building the custom transmission you need to have it last as long as the Cummins powering it.
We work on the following Cummins transmissions:
