7A1-38 CONSTRUCTION AND FUNCTION
P Range
Though the driving force of the input shaft is transmitted to the rear sun gear and reverse & high clutch drum,
the driving force is not transmitted to the output shaft since all of the clutches and brakes are not engaged.
Therefore, the vehicle can move at this condition. However, since the output shaft is mechanically locked
with the parking pawl, the rear planetary carrier and front internal gear are locked. For this reason, the
vehicle does not move.
CONSTRUCTION AND FUNCTION 7A1-39
N Range
Though the driving force of the input shaft is transmitted to the rear sun gear and reverse & high clutch drum,
the driving force is not transmitted to the output shaft, since all of the clutches and brakes are not engaged.
Therefore, the vehicle can move at this condition.
7A1-40 CONSTRUCTION AND FUNCTION
Reverse Gear in Range
The driving force from the input shaft is transmitted to the rear sun gear and reverse & high clutch drum. In the R
range, the reverse clutch is engaged and the driving force is transmitted to the front sun gear and rotates it
clockwise. The low & reverse brake is also engaged and the front planetary carrier is fixed so that the front pinion
gear does not rotate clockwise but can rotate counterclockwise. As a result, the output shaft rotates
counterclockwise and the vehicle goes back.
