The PCM turns shift solenoid valve C OFF, and controls A/T clutch pressure control solenoid valve A to release LS A
pressure (56). Shift solenoid valves A and B keep ON. Releasing LS A pressure in the CPC valve A releases CPC A
pressure in the 1st clutch pressure circuit. Shift solenoid valve C is turned OFF, and SH C pressure (SC) is applied to
the right side of shift valve C. Then shift valve C is moved to the left side to switch the port of line pressure and CPC
pressure. The 2nd clutch pressure is changed to line pressure mode, and the 2nd clutch is engaged securely. The CPC
B pressure (5D) stops at shift valve B.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicate direction on the hydraulic circuit.
