The line pressure is controlled by the TCM as follows to meet varying operating conditions.
- The TCM receives throttle angle signals, and the TCM sends a control signal to the line pressure linear solenoid. The pressure from the line pressure linear solenoid is sent to the valve where the line pressure is regulated. The valve adjusts the oil-pump-generated line pressure to make the line pressure matched to the driving condition.
