Third Gear (S Range)

Outline

• With shift solenoids A and C OFF, only C is ON in third gear, and the reduction timing solenoid is OFF in third

gear. (same as D range in the third gear)

• The operation of the front planetary gear and rear planetary gear of the S range in third gear is the same as that

of D range in third gear. However, since the reduction timing solenoid is OFF, the reduction timing valve is

switched to adjust the reduction reducing pressure higher and engage the reduction brake, resulting in engine

braking being applied.

• Line pressure is also switched to high pressure before cut back to prepare for engine braking.

Operation

• The driving force of the input shaft is transmitted in two directions: to the rear sun gear which is permanently

engaged with the input shaft, and, when the high clutch is engaged, to the reverse and high clutch drum, high

clutch hub, front planetary carrier, low clutch drum, and then the rear internal gear via low clutch.

• The rear sun gear and rear internal gear rotate counterclockwise at the same speed as the input shaft.

• As the rear pinion, which is positioned between and rotates together with rear sun gear and rear internal gear,

the rear planetary carrier also rotates counterclockwise at the same speed to transmit the driving force to the

output gear.

• The driving force transmission in reduction gear is the same as that in first gear.

• During deceleration, engine braking is not applied for the same reason as that of L range HOLD in second

gear.
