Torque Converter
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The torque converter transmits and multiplies torque. The torque converter is a device which includes 4 elements:
- The impeller assembly
- The turbine assembly
- The reactor stator assembly
- The clutch and damper assembly
The standard torque converter components operate as follows:
- Rotation of the converter housing and impeller set the fluid in motion.
- The turbine reacts to the transmission fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
- The reactor stator redirects transmission fluid going back into the impeller, providing for torque multiplication.
- The clutch and damper assembly dampens powertrain torsional vibration and provides a direct mechanical connection for improved efficiency.
- Power is transmitted from the torque converter to the planetary gearsets and other components through the input shaft.
