R Position
R POSITIONThe driving force of the turbine shaft is transmitted to the reverse and forward drum, and then to the large sun gear through the reverse clutch, causing the large sun gear to rotate counterclockwise.
The pinion gear of the planetary gear, however, does not revolve around the large sun gear because the planetary carrier is locked by the low and reverse brake.
As a result, the internal gear rotates clockwise due to the planetary gear set operation, and the driving force is transmitted to the driving wheels.
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 the manual valve position line pressure (7) is transmitted to (6), which engages the low and reverse brake. Line pressure (6) also engages the reverse clutch and N-R accumulator. Line pressure (6) also works on the pressure regulator valve, causing an increase in line pressure (7). Line pressure (7), driven to the pressure regulator valve, is transmitted to torque converter pressure (23) and sent to the torque converter through the torque converter clutch control valve.
