The 68RFE transmission, introduced by Chrysler in 2007, was designed to complement the 6.7L Cummins engine. It features six forward gears, including two overdrive gears, which help manage power and torque effectively.
The SunCoast 68RFE Category 4 Transmission is a top-tier upgrade for those requiring enhanced performance and durability. The transmission includes the SunCoast V2 billet drum, which offers a 24% increase in hydraulic clamping force compared to the factory component. This drum features a new lip seal style and a quad-ring design, which helps maintain compression during high RPMs, ensuring consistent performance.
The upgraded 2C clutch set features a billet piston, allowing for an additional clutch. This upgrade increases the surface apply area and reduces the risk of overheating and premature failure, making it a more robust option for high-torque applications.
The SunCoast Ducenti valve body is calibrated to 200psi, which improves shift precision and addresses hydraulic circuit issues for more reliable operation. The included billet triple-disc torque converter is designed with furnace-brazed fins, hardened turbine splines, and carbon-graphitic clutches to ensure accurate lock-up and durability. The billet stator in the torque converter enhances turbine slip control, making the transmission suitable for various heavy-duty applications, including towing and off-roading.
The Deep Mag Hytec pan, equipped with a Zero Cavitation filter kit, ensures better fluid management and cooling. With a capability of handling up to 950 horsepower, this transmission provides the strength and reliability needed for extreme conditions while maintaining everyday drivability. The 12-month unlimited mileage warranty on competition units offers additional assurance of its quality and performance.
