Torque Converter: Notes
WARNING: This page is about a different car, the 2007 Lincoln Navigator L and 2007 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The torque converter is a 3-element unit containing a dual-plate clutch. The clutch can be controlled and engaged in any gear 1st to 6th. Calibration parameters may be set to allow lock-up in a higher gear only. The clutch is applied by removing fluid pressure from one side of the plate. The torque converter transmits and multiplies torque. The torque converter includes the following 3 elements:
- Impeller assembly
- Turbine assembly
- Reactor 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.
- Power is transmitted from the torque converter to the planetary gearsets and other components through the input shaft.
