• The oil pump, mounted behind the torque converter, is driven directly by the torque converter.
• Inner and outer rotors are built into the pump housing in the oil pump.
• The inner rotor is driven by the torque converter in the same rotational direction as the engine.
• When the inner rotor in the oil pump rotates, ATF is drawn from the oil pan to the oil pump and then discharged to the pressure regulator valve.
• The amount of ATF discharged is proportional to the rotational speed of the torque converter.
