The PCM turns the shift solenoid valve C ON, and controls A/T clutch pressure control solenoid valve B to release LS B

pressure (57). Shift solenoid valve A keeps ON, and B keeps OFF. Releasing LS B pressure in the CPC valve B releases

CPC B pressure in the 2nd 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 line pressure and

CPC pressure. The 3rd clutch pressure is changed to line pressure mode, and the 3rd clutch is engaged securely. The

CPC A pressure (4A) stops at shift valve E.

NOTE: When used, ''left'' or ''right'' indicates direction on the hydraulic circuit.
