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 mode 1GR).

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.
