Why Does My Car Say Check Transmission?

When you see the “Check Transmission” light on your car’s dashboard, it can be a worrisome sight. After all, your transmission is a vital part of your car, and you don’t want to have to deal with any problems with it. But what does this light actually mean, and what should you do if you see it?

In this article, we’ll take a look at some of the most common reasons why your car might say “Check Transmission,” and we’ll provide you with some tips on what to do if you see this light.

Common Causes of the “Check Transmission” Light

There are a number of different things that can cause the “Check Transmission” light to come on. Some of the most common causes include:

Low transmission fluid. Transmission fluid is essential for keeping your transmission running smoothly. If the fluid level is low, it can cause the transmission to overheat and malfunction.
Dirty transmission fluid. Over time, transmission fluid can become dirty and contaminated with metal shavings and other debris. This can cause the transmission to shift gears roughly or even slip out of gear.
Faulty transmission sensors. The transmission relies on a number of sensors to monitor its operation. If one of these sensors fails, it can send false information to the transmission computer, which can cause the “Check Transmission” light to come on.
Mechanical problems. In some cases, the “Check Transmission” light can be caused by a mechanical problem with the transmission itself. This could be anything from a worn-out clutch to a broken gear.

What to Do If You See the “Check Transmission” Light

If you see the “Check Transmission” light on your car’s dashboard, it’s important to take action immediately. Here are some things you should do:

Check the transmission fluid level. The first thing you should do is check the transmission fluid level. If the fluid level is low, add more fluid until it reaches the proper level.
Have the transmission fluid changed. If the transmission fluid is dirty, it should be changed. This is a relatively simple and inexpensive procedure that can help to prevent further problems.
Have the transmission sensors checked. If you suspect that a faulty sensor is causing the “Check Transmission” light to come on, have the sensors checked by a qualified mechanic.
Have the transmission inspected. If you’ve tried all of the above and the “Check Transmission” light is still on, it’s time to have the transmission inspected by a qualified mechanic. This will help to identify any mechanical problems that may be causing the light to come on.
