ATS Aisin AS69RC Transmission

Born from a legacy of medium-duty excellence, the ATS Aisin AS69RC transmission emerges as a powerhouse in the realm of automatic transmissions. Debuting in the 2013 Ram 3500 HD, this 6-speed marvel builds upon the solid foundation laid by its predecessor, the AS68RC, to set new benchmarks in performance and durability. Exclusive to the High Output variant of the 6.7L Cummins engine, the ATS AS69RC asserts its dominance as one of three transmission options offered in the 2013 Ram lineup. What distinguishes this transmission is its commanding presence, surpassing both the AS68RC and 68RFE counterparts in size and ruggedness. At the heart of the ATS AS69RC lies a focus on torque. Featuring a TripleLok or 5 Star torque converter, depending on the transmission stage, ATS ensures seamless power transfer with enhanced performance. The TripleLok converter boasts additional clutch plates, while the 5 Star converter, four times larger, eliminates any chattering for a smooth and reliable power delivery. Addressing concerns with the factory torque converter, the 5 Star Converter features a full billet construction reinforced with a billet piston and clutch, alongside an encapsulated piston design, guaranteeing unparalleled reliability. With heavy-duty clutch components throughout, ATS engineers meticulously redesign the transmission body, fortifying valves prone to hydraulic leaks and ensuring resilience against potential vulnerabilities. Each valve body undergoes rigorous testing and calibration on the Hydrotest valve body test stand, which guarantees precision and reliability under the most demanding conditions. The redesign extends to the K2 and K3 clutch packs, where increased clutch counts provide extra capacity to handle elevated power levels and heavy loads with ease.
