Overview of Valve Body
The valve body contains a collection of passages that route fluid to specific locations inside the transmission. Valves and check balls block or allow fluid flow to the different passages as needed. Many of the valves used in modern transmissions are electronically-controlled solenoid valves. The valve body is usually attached to the case with bolts, and it can be made of either cast aluminum or cast iron.
Types of Valve Bodies
Electronic Valve Body
An electronic valve body uses electronically-controlled solenoid valves to direct fluid flow through the valve body. A computer, which is usually called the transmission control module, operates the valves based on input from various sensors.
Hydraulic Valve Body
Older vehicles do not have electronic transmission controls. As such, the valve body is a purely mechanical device. Inside the valve body, throttle valve hydraulic pressure works against governor pressure to control shift valve movement.

Components of Valve Body
Solenoids
Solenoids are electrically controlled valves that regulate the flow of transmission fluid within the car's valve body. They receive signals from the car's ECU to open or close the valves, allowing hydraulic pressure to activate specific clutch packs or bands for gear shifting. In addition, they regulate the fluid pressure for precise and smooth control of the gearing system.
Check Balls
The check balls are small spherical features that assist in regulating fluid movement within the valve's body. They act as a one-way valve, ensuring a unidirectional flow of the fluids. Therefore, they could prevent backflow, preventing pressure loss.
Passages and Channels
The passages and channels refer to the pathways within the valve body. They enable the smooth flow of hydraulic fluid to other components of the vehicle's transmission system, including the solenoids, bands, and clutch packs. These channels ensure an appropriate amount of fluid reaches these comments at the right time for smooth and precise operation.
Separator Plates
The separator plates are thin metal sheets between the valve body sections. This metal guides fluid flow between the upper and lower valve body sections while also regulating fluid flow and pressure. Therefore, they enhance precision in gear shifting.
Material of Valve Body
Some commonly used carbon steel materials for valve body are: casting steel ASTM A216 with grades WCA, WCB and WCC, forging steel ASTM grade A105/ A105N, and low temperature carbon steel (ASTM A352 LCB, LCC, ASTM A350 LF2).
When selecting material for the valve body, based on the material processing methods, there are both forged and casted steel. For a particular specification and grade of forged steel, there is a corresponding casted steel with same chemical components. These can be used equivalently for chemical and mechanical properties. However, forging steel provides better uniformity of composition and structure than casted steel.
ASTM A105/A105N steels are suited for fluid flow requiring assured performance, tight shutoff, constant torque, and no maintenance. ASTM A105 is the most used carbon steel forging material grade in manufacturing forge piping components such as valves. This carbon steel grade is used for ambient and higher temperature service in pressure systems. The 'N' in A105N stands for 'normalization' of A105. The normalizing heat treatment will ensure the forging has superior properties to the 'as forged' material.
ASTM A350 Grade LF2 is a low temperature carbon steel suitable for lowest temperature of -46°C in piping systems when there is a possibility of process fluid temperature falling below -29°C during operation.
