P Position, N Position

P POSITION, N POSITION
The driving force of the turbine shaft is transmitted to the reverse and forward drum. None of the clutches are operating, however, so this force is not transmitted to the output gear. Therefore, the vehicle cannot move. The output gear is locked because the output shell is mechanically locked by the parking pawl. (In P position)





Hydraulic pressure operation
Line pressure (7) generated in the oil pump is adjusted by the pressure regulator valve and transmitted to the manual valve, throttle valve, 1-2 shift valve, 2-3 shift valve, 3-4 shift valve, torque converter clutch control valve, 1-2 accumulator, 2-3 accumulator, and N-D accumulator. Due to manual valve position, line pressure (7) is prevented from reaching other paths. Due to the pressure regulator valve operation, line pressure (7) is transmitted to torque converter pressure (23) and sent to the torque converter through the torque converter clutch control valve.
