The PCM turns shift solenoid valve C ON, and controls A/T clutch pressure control solenoid valve A to release LS A
pressure (56) in CPC valve A. Shift solenoid valve A remains ON, and shift solenoid valve B remains OFF. Releasing LS
A pressure (56) in CPC valve A releases CPC A pressure in the 4th clutch pressure circuit. Shift solenoid valve C is
turned ON, and SH C pressure (SC) in the right side of shift valve C is released. Then shift valve C is moved to the right
side to switch the port of line pressure and CPC pressure. Line pressure (4) from the manual valve becomes 5th clutch
pressure (50) at the manual valve, via shift valves C, B, and A, and flows to the 5th clutch. The 5th clutch pressure is
changed to line pressure mode by switching the position of shift valve C. The 5th clutch is engaged securely, and the
1st clutch is also engaged. No power is transmitted because of the one-way clutch.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
