Goerend Triple Disc Torque Converter - 6.6 Duramax (2020-2023)

Our transmission system is meticulously designed and manufactured entirely in-house, ensuring comprehensive control over quality and performance. Each component undergoes rigorous testing on our in-house dynamometer to evaluate K-factor and torque ratio, guaranteeing optimal functionality. The billet steel cover, crafted from steel forgings to minimize porosity, offers robustness and versatility with its multi-bolt pattern. Featuring a billet steel piston with a complete damper assembly, our system effectively insulates the driveline from shock induced by crank pulses, thereby extending the lifespan of both converter and transmission. The stator, with its dual Torrington bearing design and lugged races, incorporates a patented internal design that ensures precise lockup without requiring throttle modulation.

Additionally, it is engineered to enhance rotation during coupling mode, creating a venturi effect to amplify torque multiplication. Our transmission system also includes proprietary high-performance multi-disc lockup clutches and a turbine that is TIG welded, furnace brazed, and silicon bronze reinforced, ensuring durability and efficiency. Precision engineering, such as computerized robotic welding and accurate balancing, guarantees consistent quality and performance. With meticulous features like below 0.005 blueprinted runout tolerances, blueprinting of internal clearances, and thorough pressurization and leak testing, our transmission system stands as a pinnacle of reliability and performance. Furthermore, components such as the 4140 hardened turbine hub, 4140 flanged impeller hub, and accurately designed pilot further contribute to its durability and functionality.
