Valve body HONDA CR-V 1997 RD1-RD3 / 1.G Owner's Guide

Main Valve Sody
The main valve body houses the manual valve, the 1-2 shift valve. the 2nd orifice control valve. the CPB valve, the modu-
lator valve. the servo control valve. and the relief valve. The primary functions of the main valve body are to switch fluid
pressure on and off, and to control the hydraulic pressure going to the hydraulic control system.
