OUTLINE

• The PCM, which is integrated with the PCM for engine control, is adopted for transale control. The PCM
outputs the control signal to the engine and the transale according to the signal from each sensor and/or
switch.
• Due to the adoption of the line pressure adjusting control by the linear type pressure control solenoid and the
clutch engaging pressure control by duty-cycle type shift solenoids A, B, and C, ecellent shift quality is
obtained.
End Of Sie
• Transmits input torque from turbine shaft to front sun gear
• Operates in forward range of first, second, or third gear position
• Transmits input torque from turbine shaft to rear planetary carrier
• Operates in forward range of third or fourth gear position
• Transmits input torque from turbine shaft to rear sun gear
• Operates when vehicle is backing
• Locks rotation of reverse drum, and fies rear sun gear
• Operates in second or fourth gear position
• Fies rotation of front internal gear
• Operates when vehicle is backing or in first gear position (L range, HOLD)
• Locks counterclockwise rotation of front internal gear in first gear position
• 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.
