Transmission Valve Body

Material: ADC12
manufacturer: NINGBO JINYAO MACHINERY Co. LTD
Part name : Transmission Valve Body
Cavity : 1
Injection: High-pressure die casting

Application: The transmission valve body (also known as the hydraulic control unit) is the precision “brain” of an automatic transmission system. It is a complex labyrinth of channels, valves, solenoids, and sensors typically manufactured as a high-pressure die-cast aluminum component. Its core function is to intelligently direct the flow of pressurized transmission fluid (ATF) to engage specific clutches and bands, thereby controlling gear shifts, torque converter lockup, and lubrication based on electronic inputs from the vehicle’s Transmission Control Unit (TCU).
