Torque Converter: Description and Operation
5R55S - Automatic Transaxle/Transmission
Torque Converter
The torque converter transmits and multiplies torque. The torque converter is a 4-element device:
^
Impeller assembly
^
Turbine and damper assembly
^
Reactor assembly
^
Clutch
The standard torque converter components operate as follows:
^
Rotation of the converter housing and impeller set the transmission 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 redirects transmission fluid going back into the impeller, allowing 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.
