Description
Line pressure is basically controlled by pump output and the pressure regulator valve. In reverse and low, line pressure is boosted by the reverse boost valve. In addition, line pressure is also boosted with the selector in the neutral, drive and reverse positions by the modulator. Pressure in these positions should increase as the throttle is opened due to the reduction in vacuum applied to the modulator valve.
