The 68-RFE transmission in the Dodge Ram 6.7L Cummins was originally designed as an economical option, which limited the quality of materials and components used. This design makes the factory transmission prone to failure under increased power and torque. The ATS 68RFE Performance Transmission Upgrade addresses these weaknesses, delivering a comprehensive solution for improving performance and reliability.

Key upgrades include recalibration of the hydraulic circuits, which ensures the correct apply and release rates for clutch packs. The transmission’s clutch packs are enhanced with single-sided and double-sided friction plates, increasing the surface area by up to 34% in critical clutch packs. This results in better clutch control and improved performance under high-power conditions.

The pump assembly has been redesigned to prevent overpressure, regulate line pressure, and improve cooling and lubrication. The valve body, the heart of the transmission, has been modified to improve hydraulic integrity, allowing for smoother and more precise shifts. These modifications ensure better durability and more efficient power transfer, particularly in high-performance or towing situations.

Weak hard parts, including the factory low sprag, are replaced with a stronger roller clutch design. The input shaft, forward hub/shaft, and intermediate hub/shaft are reinforced to handle higher torque, and an optional 300M billet input shaft is available for extreme applications.

The upgrade package also includes the option for a heavy-duty transmission pan, which adds 5 quarts of ATF and acts as a girdle to reinforce the transmission case. This helps reduce flex and ensures cooler operation, further increasing the transmission’s longevity.

With the ATS 68RFE Performance Transmission Upgrade, your transmission will be capable of handling the increased demands of high-torque applications, providing smoother shifts, improved durability, and reliable performance.
