The valve body acts as the control center of the automatic transmission, it contains a maze of channels and passages that direct the transmission fluid through valves to control the various clutches, bands and drums that change gears. Vehicles have a number of sensors that are monitoring vehicle speed, engine load and throttle position and send this information to an onboard computer, which in turn communicates with the valve body in order to shift up and down between gears. When a shift is needed, valves open and close to direct transmission fluid to the appropriate area to make the gear change occur. Transmission fluid, unlike motor oil, is more than just a lubricating fluid; it’s a hydraulic fluid. The transmission fluid flowing through the valve body is under tremendous pressure, which in turn generates heat. As the soft parts in the transmission break down, they leave small particles in the fluid as contaminants, which becomes abrasive. 🎗 Share, Comment, and save for more people to see.
