Throttle Pressure Control

In accordance with the throttle position and the selected gear position the throttle position is controlled by the TCM.

Line Pressure Control

• Engagement pressure control when shifting

  TCM controls the energizing current of the line pressure control solenoid valve assembly SLT (312) to reduce the shift shock and the output of the throttle position for each shift.

• Increase line pressure with low temperature

  When the transmission oil temperature is below 10 degree C (50 degree F) and the vehicle speed is below 5 km/h (3 mph), the TCM sends signal to the line pressure control solenoid valve assembly SLT (312) to increase the pressure to reduce the shift times. N to D and N to R
