Valve Body
WARNING: This page is about a different variant/trim than selected.
The valve body contains 6 solenoid valves:
- three pulse width modulation (PWM) solenoid valves,
- two shift solenoid (on/off) valves,
- one main regulating valve (variable force solenoid).
The individual clutches and bands are supplied pressure from the PWM solenoid valves and the shift solenoid (on/off) valves and thus the gears are shifted.
The PWM solenoid valves allow direct actuation of the clutches and bands to make sure extremely smooth gear shifting through precise pressure regulation.
The shift solenoid (on/off) valves switch the hydraulic path to the clutches and bands, reducing the number of required modulating valves.
The main regulating valve (variable force solenoid) makes sure that sufficient hydraulic pressure is available in all operating conditions.
