Transmission oil pump | Section 7 TRANSMISSION OIL PUMP Lesson Objectives 1. Demonstrate the measurement of the oil pump gears to determine the serviceability of the oil pump. 2. Demonstrate the measurement of oil pump bushings to determine the serviceability of the oil pump. 3. Describe the operation of the gear type oil pump. Automatic Transmissions - Course 262 81 Section 7 Purpose of the The pump used in Toyota automatic transmissions is the crescent type. Oil Pump It is designed to Provide fluid to lubricate the planetary gear set. Provide continuous fluid to the torque converter. Provide a volume of fluid to the clutches and brakes. Supply operating pressure to the hydraulic control system. Provide support for the torque converter stator stator reaction shaft as well as the front of planetary gear set. 82 TOYOTA Technical Training TRANSMISION OIL PUMP Oil Pump Operation The oil pump is driven by the torque converter. The center drive gear is driven by the torque converter drive hub. The external teeth of the drive gear mesh with the internal teeth of the driven gear causing it to rotate in the same direction. Located between the two gears is the crescent which separates the inlet of the pump from the outlet. As the gears rotate in a clockwise direction a low pressure develops on the inlet side of the pump as the gear teeth move away from each other. On the other end of the crescent the gear teeth come together forcing the fluid through the outlet. Oil Pump Crescent Driven Gear Drive Gear Driven Gear Drive Gear Stator - Shaft - Sub-Assembly Oil Pump Body The pump therefore controls the volume of fluid being delivered. Pressure is determined by the amount of leakage and controlled drains on the outlet circuits and engine speed. The pressure regulator valve in the valve body controls pressure by allowing for leakage based on vehicle speed and engine load. Maximum pressure is regulated by the pressure relief valve that allows for leakage when the oil pressure overcomes the tension of a
