|
The solenoid is controlled by the control module with a 300 Hz PWM signal. It is controlled by variations in current and is in the first instance dependent on the throttle position.
|
Solenoid SLT
Requested pressure
|
bar
|
|
|
The TCM calculates the desired value of hydraulic pressure which must be achieved by the valve. The value is the transmission system pressure. The value is controlled so that it is not higher than that which at the present time is required by the clutch or brake in the transmission.
