Automatic Transmission Auxiliary Oil Pump

The function of the oil pump of the transmission is to provide hydraulic pressure to operate the control valve and clutch, provide a quantitative supply of gear oil in the transmission and differential boxes, and send the transmission oil to the cooler for circulation and heat dissipation. The following is a partial introduction to the oil pump: The oil pump is the power source of the entire hydraulic system of the automatic transmission, and is generally directly driven by the engine. All automatic transmissions have a front pump driven by an engine, and some transmissions also have a rear pump driven by an output shaft. The commonly used oil pumps include internal gear oil pumps, rotor type oil pumps, and vane type oil pumps. There are two oil pumps in the gearbox, which are installed in an assembly and separated by a partition between them. They operate at the same speed and rotate at the same speed as the engine.
