The ATS Five Star™ is a revolutionary Torque Converter that utilizes all of the technologies of a traditional torque converter plus the innovative ATS Viskus Clutch Drive. The ATS Viskus Clutch Drive is the heart of the ATS Five Star™ torque converter.

The ATS Viskus Clutch Drive, along with the fluid-coupling portion of the torque converter, share in the increase of transfer of power through the torque converter. Unlike other torque converters relying on fluid transfer from the impeller to the turbine via the stator, the Five Star™ utilizes ATS Viskus Clutch Drive technology that transfers rotational energy from the engine to the transmission. When the Torque Converter Clutch is commanded to come on, the 5 clutch plates provide a 100% mechanical engagement ensuring no plate slippage during lockup, even at power levels in excess of 2000 foot pounds of torque!
