It is a mechanical switching valve that routes compressed air to the correct port on the transmission, actuating the shift mechanism. Over time, internal seals can wear or the valve can stick, causing hard shifting or air leaks, so it's typically replaced during transmission repairs or when air is escaping from the valve body. This listing does not include a shift diagram or knob; it consists of the valve assembly with a manufacturer's logo medallion.
