Engine torque applied to the pump generates a given amount of energy in the oil projected from the pump into the turbine. As this occurs a greater amount of front pump output is by-passed until at approximately 45 MPH the entire output is by-passed. A bushing in the ring gear provides a bearing between the gear and carrier so that each part can rotate independently of the other. Oil passing through the metering orifice surrounding the check ball retaining pin then builds up pressure in the accumulator to hold the piston down and to maintain the pressure required in the clutch apply chamber to insure solid engagement of clutch. As explained later (subparagraph e), reverse is obtained by holding the ring gear stationary. Copyright 2023, Antique Automobile Club of America. Low range can be used to obtain additional engine braking when descending steep grades. The oil enters the secondary stator nearly parallel to the entrance ends of its blades. All parts in the torque converter are lubricated by the oil which completely fills the converter. In Neutral and Parking oil pressure is cut off from the direct drive clutch so that clutch is disengaged. If a design change which affects interchangeability of parts goes into production during the day, the next highest number is used for the balance of the day, starting with the first transmission which contains the new parts. In Parking, Neutral and Direct Drive the valve regulates pump pressure to 80-90 psi. The greatly increased energy in the spinning flywheel of oil then projected into the turbine produces a corresponding increase in the impulsion and reaction forces upon the turbine blades.
