“Valve body” is one of those nebulous car terms you hear all the time, but nobody seems to really know what it is. At Harold's Used Auto Parts Inc in Philadelphia, PA, we know exactly what a valve body is, what it does, and are well equipped to address any issues your valve body may be experiencing.

You can almost consider a valve body to be the control center of your transmission; in a way, it’s almost even computer-like but operates on principles of pressure and hydraulics. If you look at one, it will look like a literal maze of tiny passages, check valves, and small openings.

However, exactly how a valve body works isn’t necessarily important, for the intents and purposes of this article. What you really need to know is what it does.

A valve body is more or less responsible for the way your transmission behaves. It is the input center for activating drive or reverse in your transmission, shifting gears, and telling the transmission when to shift. Through a series of different passages and fluid entry and escape points, the valve body builds, relieves, and delivers hydraulic pressure to the correct locations in the transmission, at exactly the right time. A fully functional valve body dictates how and when your transmission shifts.

Fortunately, our professional technicians specialize in the intricacies and complications of automatic transmissions and can diagnose or repair a valve body issue in no time.
