8 Tips for Extending the Life of Your Car’s Transmission

If there’s one thing you need to check regularly in your vehicle, that would be your transmission. It is essential to keep it in good working order whether you have a brand new or used vehicle

At Rodney Auto Centre, we come across transmission problems that can be easily avoided should you take care of them on a regular basis. In addition, a well-maintained transmission can last many years, but paying attention to it can lead to costly repairs or replacement.

Here are some tips for extending the life of your car’s transmission:

1. Regular Maintenance

The first step in keeping your transmission in good working order is to schedule routine maintenance. This includes frequent oil changes, checking and replacing the transmission fluid, and ensuring that all related filters are clean. Your transmission needs to be serviced according to the manufacturer’s recommended schedule, which can be found in your owner’s manual.

2. Pay Attention to Warning Signs

Your car will often give you warning signs when something is wrong with the transmission. These signs can include strange noises, slipping gears, or difficulty shifting. When you already feel something is wrong or see any warning signs, it’s essential to check your transmission as soon as possible. Ignoring these warning signs can lead to severe damage that can be costly.

3. Keep Your Transmission Cool

Your transmission generates a lot of heat and needs to be cooled to function correctly. Ensure that your transmission cooler is in good working order and that enough transmission fluid flows through it. Also, ensure that your radiator works perfectly and that enough coolant flows through it. This will help to keep your transmission cool and running smoothly.

4. Drive Carefully

The way you drive can have a significant impact on the life of your transmission. Avoid excessive speeding, sudden stops, and hard acceleration. These actions put extra stress on the transmission and can lead to damage. It’s also important to shift gears smoothly and avoid over-revving the engine.

5. Check for Leaks

Transmission fluid leaks can be a big problem and should be addressed immediately. Remember that with vehicles, leaks are indicators of a problem somewhere, and best not to ignore them. Regularly check your transmission fluid level and look for any signs of leaks.

6. Use the Right Transmission Fluid

A suitable transmission fluid for your vehicle is essential. The type of fluid recommended by the manufacturer can be found in the owner’s manual. You will find what type of fluid you can and cannot use. Please talk to your trusted mechanic, as one wrong move can damage the transmission. If you are still under warranty, topping it up with something else could void the warranty.

7. Use Overdrive Carefully

Overdrive is a feature that allows the transmission to shift into a higher gear at lower speeds, which can help to save fuel. However, it’s best to avoid using Overdrive if you’re towing a heavy load or driving in hilly terrain. Using it carefully will help prolong the life of the transmission.

8. Avoid Extended Idling

When you leave your car idling for an extended period of time, the transmission is still working, even though the vehicle is not moving. This can lead to increased wear and tear on the transmission. Avoid prolonged idling and turn off the engine if you’re going to be parked for more than a minute.


By following these tips, you can help to extend the life of your car’s transmission and avoid costly repairs. Regular maintenance, careful driving, and paying attention to warning signs are all crucial factors in keeping your transmission in good working order. With proper care and attention, your transmission can last for many years, helping you save money and enjoy a reliable vehicle.
