When Should I Change My Transmission Fluid?

Transmission fluid provides life to your transmission system. Being a lubricant, it will keep everything running efficiently and smoothly. Of course, that is, if you keep the fluid clean and at the right levels.

To ensure your transmission system runs optimally, change the transmission fluid regularly. But how will you know the transmission fluid needs to be changed? There are no hard and fast rules of knowing when to change the transmission fluid, but there are certain signs that can show you it needs replacement.

Transmission fluid

Both the quality and quantity of transmission fluid in your car's engine matter a lot. Low quantity or poor quality fluid can cause damages to the components of the transmission system.

Changing the fluid at the right time can save you a lot in repair costs. It will also extend the lifespan of your engine, particularly the transmission system.

When Should You Change The Transmission Fluid?

The right time for changing transmission fluid varies from car to car, and it mainly depends on the type of transmission the car has. From an expert point of view, cars with automatic transmissions should have their transmission fluid changed every 50,000-100,000 kilometers. 100,000 km is quite extreme. Most experts suggest a maximum of 50,000 km (or after every two years).

For cars with manual transmissions, it is recommended that the transmission fluid should be changed every 50,000-90,000 kilometers. However, if the car is used regularly, manufacturers suggest the fluid should be changed every 25,000 kilometers.

The difference comes about because automatic transmissions and manual transmissions use different fluids.

Signs That Your Transmission Fluid Needs Replacement

It is good to know the signs that show your transmission fluid needs to be replaced. Some of these signs are:

  • Color - A fresh transmission fluid is light-red. Any change of color means it has been contaminated. A poor quality fluid looks darker.

  • Smell - A fresh transmission fluid has a sweet petroleum smell. When it smells bad or as if it is burnt, it means it is due for a change.

  • Transmission slips - When you drive a car with automatic transmission, and you notice some issues like noisy and rough shifting or transmission slipping, the problem could be with the fluid.
