Five Star Viskus Clutch Drive Torque Converter, Mixed Flow Stator, Extreme Efficiency, GM Duramax late 2010+, 6.6L LML
Standard in all transmission packages, and available individually, is the ATS Five Star Torque Converter. This torque converter is built to handle daily driving and towing duties while delivering reliable performance.
The ATS Five Star utilizes an optimized factory stall speed that features improved torque multiplication. With factory torque multiplication at approximately 1.25:1, the ATS Five Star boasts 2.4:1. This occurs when peak engine torque is achieved. Increased torque multiplication results in improved vehicle response, towing and driving ability.
Every Five Star comes standard with a 5 year / 500,000 mile warranty
When the most efficient torque converter is required, look no further than ATS' Five Star Torque Converter.
The Allison 1000 is one of the stoutest transmissions behind a light duty diesel. However, the factory converters that fail with high mileage, greater than stock power and/or frequent towing. OEM units are typically made with stamped metal components and the stall speed is not matched to the motor’s torque curve.
ATS TripleLok and Five Star converters completely eliminate these weaknesses. They feature our patented square tab clutch design (for reliability during lock-up), ATS’ proprietary clutch material, CNC cut steels, re-designed stators, Torrington bearings and stall speeds matched to the Duramax motor. Both the TripleLok and Five Star are designed to hold increase torque while efficiently transferring it to the transmission. The result is more power to the ground, lower transmission temperatures and greater overall performance.
Custom stall speeds are available for racing/sled-pulling applications. ATS TripleLok and Five Star converters come with a 5 year / 500,000 mile warranty – even for competition use.
