The solenoid valve in an automatic transmission is the core actuator of the electrical control
system. Its main function is to control the on-off and pressure of the hydraulic oil circuit through
electrical signals, thereby precisely regulating the gear shifting timing, smoothness of gear shifting,
and the engagement and disengagement of the clutch/brake of the transmission.
