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.
At low speeds the Viskus Clutch Drive design has more effect on power transfer allowing for optimal stall speed. As the engine to transmission RPM differential speed is increased the efficiency of the torque converter increases. When the transmission input speed is near equal to engine speed, fluid is reversed through the Viskus Clutch Drive. The reversal of fluid is commanded by the factory computer or an external lock-up controller such as the Co-Pilot. This fluid reversal compresses the five clutch plates providing a 100% mechanical engagement ensuring no plate slippage during lock-up even at power levels in excess of 2000 foot pounds of torque.
The ATS 3029502164 Five Star Torque Converter is a 12-bolt design.
