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
