GM / LLY Duramax / Torque Converters
TORQUE CONVERTERS THAT OFFER MORE POWER AND GREATER EFFICIENCY.


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.
