F 150 2WD Pickup V8-5.4L SOHC VIN 5 (2004)
The torque converter transmits and multiplies torque. The torque converter is a 4-element device:
-
Impeller assembly
-
Turbine assembly
-
Reactor assembly
-
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 fluid motion from the impeller, transferring rotation to the geartrain through the input shaft.
-
The reactor redirects 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.
