How the ATS Mixed-Flow Stator works - TripleLok Torque Converter, Factory Stall Speed, 1994 to 2007, 5.9L Cummins, Dodge 47R-H/47-RE/48-RE Transmission

The stator design controls stall speed and determines torque multiplication of a Torque Converter. The ATS Mixed FLow Stator is designed to be most efficient through the torque band of the Diesel engine. Along with the Five Clutch Viskus Drive lockup section and full billet cover and piston construction, the five clutches of the Five Star Viskus Clutch Drive Torque Converter are designed to transfer power through the converter along with the conventional fluid coupling portion of the torque converter. By designing a stator that works with the Viskus Clutch Drive you have that smooth power transfer that has not been possible in the past.

The efficiency of the converter eliminates the heat and contamination that exist in the factory converter. When other features are desired, like engine braking, enhanced shift strategies, increasing the power handling capability of the transmission etc., you will need to add a few more products. An example of this would be an exhaust brake. The exhaust brake does an excellent job of slowing the engine, but it does nothing to transfer the retarding force (braking effort) of the engine to the wheels when the torque converter is not locked up. The Five Star Viskus Clutch Drive aids in this condition due to it's unique Viskus Clutch Drive technology and the design of the Mixed Flow stator.In order to effectively use 100% of the retarding force of the engine, you must lockup the torque converter clutch. To lockup the converter clutch, you must send the signal to the valve body in the transmission. Using stock electronics, the lockup signal to the transmission will not be sent when the accelerator pedal is at the idle position, creating another problem.

The ATS Co-Pilot comes in handy for this; it sends the signal to the converter clutch via the valve body to turn on the lockup clutch of the converter along with sending the signal to the exhaust brake. The Co-Pilot also automatically releases the brake and lockup clutch when the desired release speed is reached.
