The PCM controls the shift solenoid valves and the A/T clutch pressure control solenoid valves. The conditions of the
shift solenoid valves and the positions of shift valves are as follows:
• Shift solenoid valve A is turned ON, and shift valve A stays on the right side.
• Shift solenoid valve B is turned ON, and shift valve B stays on the right side.
• Shift solenoid valve C is turned OFF, and shift valve C stays on the left side.
The PCM also controls A/T clutch pressure control solenoid valve A to apply LS A pressure (56) to CPC valve A. Line
pressure (4) from the manual valve becomes 2nd clutch pressure (20) at shift valve B, via shift valves C and A. 2nd
clutch pressure (20) is applied to the 2nd clutch, and the 2nd clutch is engaged. 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.
