1, change the transmission ratio to meet the needs of different driving conditions for traction,

2, to achieve reverse driving, to meet the needs of the car driving backwards.

3, interrupt the power transmission, start the engine, idle operation

4, to achieve neutral, when the clutch engaged, the gearbox can not output power

The solenoid valve is controlled by the transmission electronic control module TCU. The pressure of the basic overhead gear and shift is constant, but the opening of the solenoid valve is adjusted during the shift process to improve the smoothness of the shift. Different solenoid valves control different clutches or brakes and play a role in different gears. Each gear is controlled by one or more solenoid valves.

The transmission filter (also known as the "strainer" or "hydraulic filter") for a gearbox is a filtration element provided in a car transmission system.Its role is to preserve the oil by retaining particles and impurities that may be circulating in the system.The transmission oil in the gearbox actually lubricates the gears and other components.It is therefore important to filter out impurities, metal fragments and particles that may be circulating in the oil and damage the system.
