D Position, at top 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.

Vehicle speed is further increased, the PCM controls the CVT driven pulley pressure control solenoid valve and the CVT drive pulley pressure control solenoid valve to apply hydraulic pressure to the drive pulley and to the driven pulley. The drive pulley receives high pressure and the driven pulley receives low pressure. The drive pulley provides the steel belt a large-diameter contact and the driven pulley provides a small-diameter contact, and the result is a high pulley ratio. Hydraulic pressure remains applied to the start clutch and the forward clutch.
