As you probably already know, your vehicle's transmission is one of its most important parts. For it to run properly, however, you have to make sure that there is enough transmission fluid and that the transmission fluid is in good shape. Luckily, there are a few things that you can look for if you are afraid that there is something wrong with your transmission fluid.

These are a few signs that you might need to have your transmission fluid looked at; for example, you might need to add more, have it flushed or have a transmission fluid leak repaired:

1. You Spot Transmission Fluid Underneath Your Car

Although it might not seem abnormal to see some liquid underneath your car -- such as if you see water from your air conditioner -- you should always look out for transmission fluid leaks. Luckily, transmission fluid is relatively easy to identify; it is generally red in color, and it should have a rather sweet smell.

If it is old and needs to be flushed and replaced, however, it might be much darker in color and have a burnt appearance. If you spot an unfamiliar liquid underneath your car, there is a good chance that there is a leak that needs to be repaired. If it isn't, then all of your transmission fluid could run out.

2. Your Transmission Fluid Levels are Low

Periodically, you should check the transmission fluid levels in your vehicle. To do so, you should make sure that your vehicle is still running and that your engine is warm, and you should find the dipstick to check for recommended transmission fluid levels. This is a simple guide for how to do so on an automatic vehicle, although you can find additional information in your car's owner's manual.

3. Your Transmission Fluid is Burnt

Burnt transmission fluid can be an indication of a problem that needs to be resolved right away, such as using the wrong type of fluid. If you notice a burning smell coming from under the hood of your car, there is a good chance that your transmission fluid is burning, which means that you need to have your vehicle looked at by a professional at a transmission repair shop.

Transmission fluid helps keep your transmission properly lubricated and can cause a lot of problems if it isn't present and in good shape. These are a few signs that you are dealing with a potential transmission fluid issue. If you notice any of these signs, it's important to take your car to the shop now, before you have to deal with any expensive transmission-related issues.
