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, fourth or fifth gear position.
Reverse clutch
• Transmits the input torque from the turbine shaft to the rear sun gear.
• Operates when the vehicle is backing up.
Direct clutch
• Engage the secondary planetary carrier and the secondary sun gear.
• Operates in the fifth gear position.
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 (M range 1GR).
Reduction brake
• Fixes the rotation of the secondary sun gear.
• Operates when the vehicle is backing up.
• Operates in the first, second, third or fourth gear position.
One-way clutch No.1
• Locks the counterclockwise rotation of the front internal gear in the first gear position.
One-way clutch No.2
• Operates in the first, second, third or fourth gear position.
Front planetary gear
• The front planetary gear and rear 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 primary gear.
Rear planetary gear
Secondary planetary gear
• The secondary 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.
