Reverse Inhibitor Control
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.
When R is selected while the vehicle is moving forward at speeds over 6 mph (10 km/h), the PCM commands shift solenoid valve C to remain OFF so that shift solenoid valve C pressure (SC) is not applied to the reverse inhibitor valve. Line pressure (3) stops at the reverse inhibitor valve, and is not applied to the shift fork shaft. This control does not switch to the hydraulic circuit leading to reverse while the vehicle is moving forward at speeds over 6 mph (10 km/h).
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
