Five Star Torque Converter - 2008-2010 Ford 6.4L
Five Star Viskus Clutch Drive Torque Converter, Mid-Stall w/ Extreme Efficiency Mixed Flow Stator - Wide Turbine & Impeller.

Many owners of late model 6.4-liter Ford Power Stroke Trucks are updating their trucks for increased power. With an automatic transmission this can have some unexpected and unwelcome side effects when it comes to maintaining the best drive-ability. The fluid inside the transmission's torque converter is pumped between the turbine and impeller pieces to transfer torque from the engine into the transmission and then to the wheels. The impeller, which turns at engine revolution speed, spins the hydraulic fluid, which then turns the turbine and transmission gear train. The revolution speed at which this power transfer happens is called the 'stall speed’ of the torque converter.

Once power is increased in the truck's engine, the torque converter's stall speed (R.P.M.) can in-turn be raised significantly. Since the diesel engine's peak performance takes place at lower R.P.M., this can have a detrimental and unwanted effect. ATS has alleviated this problem by re-engineering the torque converter with a wider turbine and impeller to control the hydraulic fluid. With the wider stance of these pieces, along with the stator design, the effective leverage exerted on the fluid is increased and allows the stall speed to remain at optimum R.P.M.

As with the previous Five Star Torque Converter designs, ATS provides a patented 5-disc lockup clutch pack for ultimate power transfer and strength. Stamped steel factory components, such as the cover (or shell) of the converter, are replaced with heavy duty billet-machined pieces. Plastic internals, such as washers, are replaced by H.D. metal roller bearings. Other parts which can lead to internal failure, such as the tab-fastened fins on the turbine and impeller, are brazed and reinforced for increased strength.
