D Position, at low speed range

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 D position, and uncovers the forward clutch pressure (FWD) port leading to the forward clutch. The forward clutch pressure (FWD) flows to the forward clutch, the forward clutch is engaged, and drives the input shaft and the drive pulley shaft. The drive pulley receives low pressure, and the driven pulley receives high pressure. The PCM actuates the CVT clutch pressure control solenoid valve to control start clutch pressure. The start clutch control pressure (CC) from the CVT clutch pressure control solenoid valve becomes start clutch pressure (SC) at the shift inhibitor valve, and flows to the start clutch. The start clutch is engaged, and the vehicle moves.
