2 Position

The PCM controls the shift solenoid valves and A/T clutch pressure control solenoid valves A and B. The conditions of the shift solenoid valves and the position of the shift valves are as follows:

• Shift solenoid valve A is turned ON, and shift valve A is in the right side.
• Shift solenoid valve B is turned ON, and shift valve B is in the right side.
• Shift solenoid valve C is turned OFF, and shift valve C is in the left side.

The PCM also controls A/T clutch pressure control solenoid valve A to apply the LS A pressure (56) to CPC valve A.

Line pressure (4) from the manual valve becomes the 2nd clutch pressure (20) at shift valve B, via shift valves C and A. The 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.
