R Position
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
The manual valve is shifted into the R position, uncovers the reverse brake pressure (RVS) port leading to the reverse inhibitor valve. The reverse inhibitor solenoid is turned OFF by the PCM, and reverse inhibitor pressure (RI) is applied to the right end of the reverse inhibitor valve. The reverse inhibitor valve is moved to the left side, and uncovers the reverse brake pressure (RVS') port leading to the reverse brake. Clutch reducing pressure (CR) becomes reverse brake pressure (RVS), and flows to the reverse brake via the reverse inhibitor valve. The reverse brake is engaged, and it locks the planetary carrier.
NOTE:
When used, "left" or "right" indicates direction on the hydraulic circuit.
