Shift Control





A/T CONTROL SYSTEM


Shift Control

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 characteristic is attained.






SHIFT CHANGE
The clutch is controlled with the optimum timing and oil pressure by the engine speed, engine torque information, etc.
