System Description

INFOID:0000000009948915

Driving force of engine is transmitted to wheels via torque converter, planetary gear, belt & pulley, differential
gear, and others. In addition, with mounting of parking mechanism, secondary pulley is mechanically fixed by
shifting the selector lever to “P” position.

Activation state according to each gear shifting

: Activation

Power transmission of each position

“P” position

• Driving force from input shaft is not transmitted to primary pulley because of idling caused by poor engage-

ment of forward clutch and reverse brake.

• Since the parking pole interlocked with the selector lever becomes into engagement with the parking gear

integral with the output shaft to mechanically fix the output shaft, torque from wheel is not transmitted to sec-
ondary pulley.

Planet gear

“R” position

• Driving force from input shaft rotates sun gear in opposite direction of input shaft rotation because reverse

brake is engaged and internal gear is fixed.

• Therefore primary pulley rotates in opposite direction of input shaft rotation and driving force output is in

opposite direction rotation.
