Fluid Pressure Directed In Preparation For A Shift

Line Fluid Circuit 

Line fluid from the automatic transmission fluid pump supplies constant fluid flow to various components such as the line pressure regulating valve, line pressure control solenoid, variable high clutch dam feed regulator valve, shift solenoid 2, shift solenoid 3, shift solenoid 4, shift solenoid 5, variable low clutch valve, variable high clutch valve and dampener bypass clutch valve. Line pressure is controlled by the HPCM by varying electrical current supplied to the line pressure control solenoid dependent on transmission operating conditions.
