Shifting to N from R
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
Line pressure (1) regulated by the main regulator valve flows to the shift solenoid valves. The PCM switches the shift solenoid valves ON and OFF. The conditions of the shift solenoid valves and the positions of the shift valves are as follows:
- Shift solenoid valve A is ON, and opens shift solenoid valve A pressure port (SA); shift valve A is moved to the right side by the hydraulic pressure (SA) from shift solenoid valve A.
- When shifting to N from R, shift solenoid valve B is OFF, and closes shift solenoid valve B pressure port (SB); shift valve B remains on the left side under a spring force, and shift valve C is moved to the left side by hydraulic pressure (4B) that is applied from shift valve A through shift valve B.
- When shifting to N from R, shift solenoid valve C is ON, and opens shift solenoid valve C pressure port (SC); the reverse inhibitor valve is moved to the left side by hydraulic pressure (SC) from shift solenoid valve C.
- The manual valve covers the ports leading pressure to the clutches in N, and hydraulic pressure is not applied to the clutches.NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.
