## Component description

Component | Function
--- | ---
Forward clutch | Transmits the input torque from the turbine shaft to the front sun gear. Operates in the forward range of the first, second, or third gear position.
3-4 clutch | Transmits the input torque from the turbine shaft to the rear planetary carrier. Operates in the forward range of the third or fourth gear position.
Reverse clutch | Transmits the input torque from the turbine shaft to the rear sun gear. Operates when the vehicle is backing up.
2-4 brake band | Locks rotation of the reverse drum and fixes the rear sun gear. Operates in the second or fourth gear position.
Low and reverse brake | Fixes the rotation of the front internal gear. Operates when the vehicle is backing up or in the first gear position (L range HOLD and M range).
One-way clutch | Locks the counterclockwise rotation of the front internal gear in the first gear position.
Planetary gear | The planetary gear functions as a transmission due to the engagement/ disengagement of clutches and/or brakes, converts the transmitted driving force of the turbine shaft and transmits it to the output gear.

  Note

  • All directions of rotation are viewed from the torque converter.
