Line Pressure Control
ECS009CN
●
The pressure control solenoid valve A controls linear line pressure by control signal from TCM and line
pressure for clutches and brakes to reduce shift shock.
●
This pressure control solenoid valve A controls the pressure regulator valve as the signal pressure and
adjusts the pressure of the operating oil discharged from the oil pump to the line pressure most appropri-
ate to the driving state.
LINE PRESSURE CONTROL IS BASED ON THE TCM LINE PRESSURE CHARACTERISTIC
PATTERN
In order to obtain the most appropriate line pressure characteristic to meet the current driving state, the TCM
controls the pressure control solenoid valve A current and thus controls the line pressure.
Shift Control
ECS009CO
The clutch pressure control solenoid is controlled by the signals from the switches and sensors. Thus, the
clutch pressure is adjusted to be appropriate to the engine load state and vehicle driving state. It becomes
possible to finely control the clutch hydraulic pressure with high precision and a smoother shift change charac-
teristic is attained.
Basically TCM programmed for economy mode, but TCM changes to several shift schedule automatically
according to specified condition.
