Are you tired of weak, overheating transmissions letting you down when towing heavy loads or hauling equipment? The RoadMaster Transmission Converter Package is a complete performance transmission and torque converter solution engineered for Ram 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins. This package replaces your worn or stock transmission with a heavy-duty unit built to withstand real-world towing, hauling, and daily driving. By addressing common failure points and upgrading internal components, it improves reliability and shift quality while handling elevated torque loads. Whether you’re preparing for frequent towing, heavy use, or simply want peace of mind on the road, this transmission and converter combo delivers dependable power transfer and long-term durability.

This transmission package is built from the ground up with strength and longevity in mind. The AISIN AS69RC transmission features a proprietary, hardened-billet K2 hub that resolves the notorious clutch-tooth wear issue found in many stock units, and a billet K3 drum for improved torque capacity and component strength. Clutch counts are increased in key packs to handle torque better, and an upgraded valve body with a stiffer pressure regulator spring boosts line pressure for more positive clutch engagement. A deep sump pan increases fluid capacity by 3.5 quarts for improved cooling and fluid life, and nitrile pan and PTO gaskets help prevent leaks common with OEM cork gaskets. Included with the transmission is a ProForce-style torque converter with new clutches and a sprag for strong, reliable converter performance. Designed as a complete drop-in upgrade, this package provides enhanced durability, optimized fluid management, and greater capacity than stock for drivers seeking serious transmission strength.
