The valve body function, repair and troubleshooting.

Your car’s transmission has a valve body that’s like a hydraulic regulation center controlling transmission fluid it uses to operate a network of spring-loaded valves, servo pistons and check balls. The shift valve receives pressure by the governor and the throttle valve which are supplied with fluid by the pump which is sent to its circuits. The shift valves determine when to shift gears.

By using clutches and bands with fluid going into them it uses pressure to regulate which of them open and close as the engine’s RPMs change. The ECU or TCU regulate these valves. If the car's RPMs increase the shift valve will let the automobile accelerate before it shifts. As speed increases, pressure increases depending on how fast the automobile accelerates. This dictates how fast an automobile will shift knowing if the driver wants to go quick or is just driving at a slow pace in which the transmission will up-shift sooner.
