What Does Your Transmission Do?

It is important to understand your powertrain transmission so you can realize what happens when it blows. The transmission is controlled by an assortment of sensors, but simply put, it shifts gears, controls speed, and transfers power to the wheels. 

Transmission Failure Signs

Odd Noises

Hearing any odd noises is a telltale sign that something is wrong. It could be anything from your transmission to your muffler so if you hear anything out of the ordinary, get it checked.

Check Engine Light

Almost all vehicles today have a check engine light that displays on the dash when an engine problem occurs. If you notice the light come on, this means your car is trying to tell you something. So, be proactive and remember to never ignore this issue when the light turns on!

Leaking Transmission Fluid

A transmission needs lubrication to be able to function properly. Automatic Transmission Fluid is very recognizable because of the red color and sweet smell. A burnt smell and more brownish color is also a sign that your transmission needs service.


Overheating is the biggest signs of transmission failure. It stems from the wrong type of transmission fluid or the lack thereof. If you suspect something is wrong keep an eye on your temperature gauge.

Slipping Gears

In an automatic car listen and feel for any slipping or clunking of gears when you change from park to drive and as it changes gears when you increase speed. In a manual car listen for the same things as you engage and release the clutch and when you change gears.

Total Transmission Failure

It is also possible your transmission can totally fail. In this case, your car could refuse to move, change gears, or there could be decreased or total lack of power while driving. If you are experiencing these problems take your car in immediately.  


Regular Maintenance

The most effective way to prevent transmission issues from happening is to keep up on regular maintenance. This means checking all your fluids (transmission fluid, radiator fluid, power steering fluid, brake fluid, coolant, and oil), changing your oil, and following the recommended maintenance periods from your car manufacturer.

Allow the Car to Warm Up

Similar to the human body a car needs to warm up before you take off. This will greatly increase the lifespan of your car in every aspect.

Take It Easy

If you are a city driver a lot of stop and go is very rough on your car as well as driving in severe weather conditions. To maximize the lifespan of your car try to ease in and of acceleration and understand the limits of your car.
