Hydraulic Flow: Notes
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2006 Honda Insight, 2005 Honda Insight, 2004 Honda Insight, 2003 Honda Insight, and 2002 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
As the engine turns, the ATF pump starts to operate. Continuously variable transmission fluid (CVTF) is drawn through the ATF strainer and discharge into the hydraulic circuit. Then, CVTF flowing from the ATF pump flows to the PH regulator valve and becomes pressure high (PH) pressure. PH pressure flows to the pulley control valves and then to the pulleys. The TCM actuates the solenoids to control hydraulic pressure shifting pulley ratio and engaging the start clutch.
Hydraulic pressure at the port is as follows:
HYDRAULIC PRESSURE DESCRIPTION

| CR | Clutch Reducing | RCC | Recirculation |
| DN | Driven Pulley | Rl | Reverse Inhibitor |
| DNC | Driven Pulley Control | RVS | Reverse Brake |
| DR | Drive Pulley | RVS' | Reverse Brake |
| DRC | Drive Pulley Control | SC | Start Clutch |
| FWD | Forward Clutch | SI | Shift Inhibitor |
