Automatic transmission hydraulic control unit

According to my experience in repairing cars and teaching, the hydraulic control unit of automatic transmission refers to the oil circuit or valve plate, which is installed on the oil pan and controls the oil circuit pressure of the whole gearbox. The hydraulic transmission is the core component, and the throttle oil pressure refers to one of the main control oil pressure signals on the hydraulic transmission. The throttle on the valve plate is pulled by the throttle cable to produce oil pressure called throttle oil pressure, which is used to control gear shifting. The other is that the oil pressure generated by the output shaft of the transmission is called speed-regulating oil pressure, which are the main control signals on the hydraulic control transmission.

I hope it will help you, please adopt it if you are satisfied!
