The PCM turns shift solenoid valve C OFF. Shift solenoid valve A remains OFF, and B remains ON. Shift solenoid valve
C is turned OFF, and SH C pressure (SC) is applied to the right side of the reverse CPC valve. Then the reverse CPC
valve moves to the left side, creating full line pressure. Line pressure to the 4th clutch is the same as in shifting to the
R position, and 4th clutch pressure increases. The 4th clutch is engaged with line pressure mode.
When the R position is selected while the vehicle is moving forward at speeds over 6 mph (10 km/h), the PCM outputs
to turn the shift solenoid valve C ON; shift solenoid valve A remains OFF, and shift solenoid valve B remains ON. The
reverse CPC valve is moved to right side and cover the port to stop the line pressure (3’) to the servo valve. The line
pressure (3’) is not applied to the servo valve, and the 4th clutch pressure (40) is not applied to the 4th clutch, as a
result, power is not transmitted to the reverse direction.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
