5. The ATS 5-Star Viscous Clutch Drive torque converter hold multiple patents. It's one of ATS's specialties that helped start the business and helps make the transmission packages so effective for diesel draggers and heavy load haulers.
Everything for the torque converter is built in-house, right down to the laser cutting to make the veins that are furnace-brazed and reinforced in the impellor and turbine section.
Note the thicker ATS stator, held in the left hand, compared to the stock stator (held in the right hand). The stator redirects fluid into the turbine, and the ATS unit creates better torque multiplication. The window size between the veins, along with the shape of the stator's veins, determines the stall speed of the torque converter.
