Abstract
A unique regulator valve arrangement is provided for an automatic transmission which provides variable line pressure. The line pressure is actively regulated through the regulator valve configuration with a variable force solenoid. The arrangement allows line pressure to be maintained at a minimal value according to a given condition while avoiding clutch slip.
