ATS Five Star Torque Converter

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

The Viscous Clutch Drive characteristic, along with the fluid-coupling portion of the torque converter share in the transfer of power through the torque converter. Unlike other torque converters that rely on fluid transfer from the impeller to the turbine via the stator, the Five Star utilizes viscous energy that transfers rotational energy from the engine to the transmission. When the Torque Converter Clutch is commanded to lock up, the 5 clutch plates provide a 100% mechanical engagement ensuring no plate slippage during lock up, even at power levels in excess of 2000 foot pounds of torque! We're so confident in the Five Star that it is backed by the only 3-year 150,000-mile warranty in the business.

Some of the features of the Five Star Torque Converter are:

Full Billet Steel Construction in place of cheap steel stamping
5 Disk friction surface with Patented Square Flank Drive
Stall speed is perfectly matched to engine torque curve
Mixed-Flow stator works with Viscous Clutch Drive maximizing torque multiplication
Fully welded impeller and turbine vane section
Oversized high load thrust bearings in place of plastic washers

The ATS Commander © has been developed to provide control over converter lockup in your vehicle. Factory computers are programmed to disengage lockup under many conditions that often inhibits the performance of the transmission. With a Five Star Torque Converter and The ATS Commander © in place, these non-lockup torque converter situations are no longer an issue.
