2 Major Causes of a Malfunctioning Transmission Valve


Your vehicle's transmission is one of the most crucial systems for its peak performance. A major component found in this system is the transmission valve. This device is considered to be the brain of the overall system. This is because it is tasked with directing the different fluids to their appropriate passages while also controlling the shifting of the transmission. Therefore, any underlying issues with the transmission valve will have an adverse effect on the entire transmission as well as your power steering.

Luckily, knowing what is causing a malfunction in your transmission valve and catching this issue early will ensure that you do not have to deal with extensive vehicle repairs. So what are some of the reasons why your transmission valve may begin to malfunction?

There is metallic debris in the transmission system

If there are metallic pieces of debris moving around in the various fluid passages, it will eventually begin to affect how your transmission works. This metal debris will start to impede on the shifting of the transmission, which leads to decreased pressure in the system.

The metallic debris can also begin to damage the O-rings in your transmission system, which can cause leaks to spring up in the system. Over time, the metallic debris accumulates and starts to block the fluid passages in the system. This significantly decreases the amount of pressure that your transmission needs to properly shift, and this will lead to the inability of your valve to detect that you are trying to shift gears. This manifests as rough shifting or experiencing a delay when trying to shift. Any of these symptoms should be a red flag warning you to take your car for servicing.

The transmission pump is damaged

If your transmission pump has become faulty, it will be unable to provide adequate amounts of lubrication to the transmission valve. With time, this leads to direct contact between the various metallic components of the transmission system. One of the problems that come about because of this situation is the quick wearing down of your gears. Moreover, it also causes the sticking of your gears, which would eventually lead to complete gear failure.

Lastly, insufficient lubrication poses the risk of your vehicle overheating. This is because the transmission system loses its capability to cool itself without adequate lubrication. It would be important to have the transmission pump inspected to determine whether it is causing the malfunctioning of your transmission valve.
