Stator 4R100

A stator is located between the turbine and the impeller. This component helps to reduce churning losses and enhances torque output by changing direction of ATF from the turbine to the impeller, ensuring operation of the whole mechanism and adding to engine torque. The stator works in one direction , so it either operates with the impeller or stays still. The stator either increases the torque parameter when the car runs at idle speeds, or stays inactive when the car runs at road speed.
