The PCM turns 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 remains ON, and B remains OFF. Releasing L S B pressure in the CPC valve B
releases C P C 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 of line
pressure and CPC pressure. 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.
• Hydraulic circuit shows the '98-99 models; the '00-02 models are similar.
