6.4L Five Star ‘Wide’ Torque Converter from ATS Diesel

CC | June 2, 2011

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.
