Valve Body
The valve body supplies fluid by switching the fluid circuit for the hydraulic pressure that is generated by the fluid pump. Based on the hydraulic pressure generated by the fluid pump the TCM sends control signals to the solenoid valves in accordance with vehicle conditions. Upon activation of the solenoid valve, the control hydraulic pressure to the clutch and brakes is determined (according to the equilibrium with the obtained hydraulic pressure) and gear shift and lockup are accomplished. In addition, an appropriate amount of fluid is supplied to the torque converter, planetary gears and lubricating parts.
