Solenoid Apply Chart

All gear solenoids are turned off electrically to provide clutch apply.
The line pressure solenoid is turned off electrically to provide maximum pressure boost or maximum line pressure. Normally the line solenoid is Pulse Width Modulated (PWM) to provide line pressure in a range between minimum and maximum line pressure.
The Torque Converter Clutch (TCC) solenoid works opposite of the gear solenoids. When the solenoid is turned Off electrically, the TCC is turned Off.
