The transmission valve body function, repair and troubleshooting.

Your car or truck transmission has a valve body inside it which serves as a hydraulic regulation center controlling transmission fluid which it uses to run a network of spring loaded valves, servo pistons and check balls. The shift valves inside the valve body determine when to shift gears. The shift valve receives pressure by the governor and the throttle valve which are supplied with fluid by the pump which is sent to circuits.

By using clutches and bands with fluid going into them it uses fluid pressure to regulate which ones open and close and as the engine RPMs change the pressure. The ECU or TCU regulate these valves. If the car's RPMs rev up the shift valve will let the care accelerate before it would normal shift. As speed increases, pressure increases as well depending on how fast the car accelerates dictating how quickly a care will shift knowing the driver wants to go quick or is just driving at a slow pace which the transmission will up-shift quicker and saving MPG.

If your car cannot shift into gear then a valve body and components inside may need replacing. We can diagnose this problem at The Lake Worth Transmission Repair Shop in Palm Beach County.
