Turn Extreme Horsepower Into Reliable Performance

When your Cummins build reaches the point where ordinary transmission upgrades are no longer enough, you need a package that is engineered for serious power. The Randy's Transmission Stage 3 68RFE is built for 2007.5-2018 Ram 2500 and 3500 trucks producing up to 900 horsepower while maintaining the versatility needed for towing, hauling, and high performance driving. Instead of forcing you to choose between strength and drivability, this transmission delivers the confidence to handle demanding workloads without giving up smooth operation. The included billet triple disc torque converter helps put every bit of available power to the ground with greater efficiency, making it an ideal match for modified 6.7L Cummins engines. Additionally, reinforced internal components are designed to withstand the increased torque that comes with aggressive tuning and larger performance upgrades. Whether your truck spends weekends at the track or weekdays pulling heavy trailers, this transmission is built to keep pace with your goals. It is a complete solution for owners who expect their transmission to work just as hard as the engine sitting in front of it.

Engineered With Heavy Duty Components Throughout

Every major component inside the Stage 3 68RFE has been selected to improve strength, holding capacity, and long term durability under demanding conditions. The BabyMaker 1000 billet channel plate valve body is assembled and tested in house, while billet accumulators, TransGo SSV valves, and updated pressure regulating components help maintain precise hydraulic control. A Sonnax input shaft, Randy's XD input drum, and billet triple disc torque converter work together to improve torque handling across the drivetrain. Furthermore, the upgraded steel center support with five 4C clutches and a billet piston increases clutch holding power, while fourteen low and reverse clutches, a TCS low and reverse sprag update, and a TIG welded planetary assembly strengthen critical internal areas. New Sonnax bearings, replacement bushings, OEM Mopar pressure and speed sensors, and a billet steel spin on filter adapter contribute to reliable long term operation. Randy's heavy duty injection moulded aluminum deep pan increases fluid capacity to promote improved cooling during sustained heavy use. To achieve the best results, the manufacturer also provides recommended tuning parameters for line pressure, converter lockup strategy, and low and reverse sprag operation so the transmission can be properly calibrated for its upgraded components.
