Automatic transmission oil supply system
The oil supply system of the automatic transmission is mainly composed of an oil pump, a fuel tank, a filter, a pressure regulating valve and a pipe. The oil pump is one of the most important assemblies of an automatic transmission. It is usually mounted behind the torque converter and driven by the sleeve at the rear end of the torque converter housing. When the engine is running, the oil pump is running regardless of whether the car is running or not, and provides hydraulic oil of a certain hydraulic pressure for the torque converter, the shift actuator, and the automatic shift control system in the automatic transmission. The adjustment of the oil pressure is achieved by a pressure regulating valve.
