Whenever the engine is running at idle with the selector lever in Neutral (N), oil from the pump is directed as shown.
1. Pressure Regulator Valve
2. Converter
a. Oil Cooler
b. Lubrication System

3. Manual Valve
4. Detent Valve
5. Detent Solenoid
6. Vacuum Modulator Valve
7. Front Servo

COOLING AND LUBRICATION

Oil flows from the pump to the pressure regulator valve which regulates the pump pressure. When the pump output exceeds the demand of line pressure, oil from the pressure regulator valve is directed to the converter feed passage to fill the converter. Converter return oil is directed to the transmission cooler. Oil from the cooler is directed to the transmission lubrication system.

Line pressure acts on the:
1. Manual Valve
2. Detent Valve
3. Detent Solenoid
4. Modulator Valve
5. Front Servo

Line pressure at the modulator valve is re-regulated to modulator oil which acts on the pressure boost valve, 1-2 accumulator, and primary valves. It then passes through the detent valve and 3-2 valve to the 1-2 and 2-3 valve trains.

SUMMARY
The converter is filled, and all clutches and bands are released. The transmission is in Neutral.
