7 - CRESCENT

As the torque converter rotates, the converter hub

rotates the inner and outer gears. As the gears

increases in the crescent area, and creates a suction

at the inlet side of the pump. This suction draws

fluid through the pump inlet from the oil pan. As the

clearance between the gear teeth in the crescent area

decreases, it forces pressurized fluid into the pump

outlet and to the valve body.
