P Position
The PCM switches the shift solenoid valves ON and OFF. The conditions of the shift solenoid valves and positions of the shift valves are as follows:
- Shift solenoid valve A is OFF, and closes the port of shift solenoid valve A pressure (SA); shift valve A remains on the left side.
- Shift solenoid valve B is turned ON, and closes the port of shift solenoid valve B pressure (SB); shift valve B and shift valve E remain on the left side.
- Shift solenoid valve C is OFF, and opens the port of shift solenoid valve C pressure (SC); shift valve C and shift valve D move to the right side.
- Shift solenoid valve D is turned ON, and opens the port of shift solenoid valve D pressure (SD); reverse control valve moves to the right side.
The manual valve is moved to P, and line pressure (1) becomes line pressure (3) at the manual valve. Line pressure (3) passes through the reverse control valve, and becomes line pressure (3A), then flows to the servo valve. Line pressure (3A) pushes the servo valve to the reverse position. Line pressure (3) flows to the manual valve via the reverse CPC valve and shift valve A, and stops at the manual valve. Hydraulic pressure is not applied the clutches.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
