Keep your car shifting smoothly and avoid costly repairs

When it comes to vehicle maintenance, most drivers remember to change their oil—but the transmission fluid is often forgotten. Your transmission is one of the most expensive components in your vehicle, and without clean fluid, it can quickly wear down or fail altogether.

Here’s why regular transmission fluid changes matter and how they can save you money in the long run.

What Does Transmission Fluid Do?

Transmission fluid is essential for:

  • Lubricating moving parts
  • Cooling the transmission
  • Preventing wear and corrosion
  • Enabling smooth gear shifts

Over time, the fluid breaks down and becomes contaminated with dirt and metal shavings. When that happens, it can no longer protect your transmission.

Signs Your Transmission Fluid May Need Attention

If you notice any of these, it’s time to have your fluid checked:

  • Slipping gears
  • Delayed or rough shifting
  • Grinding or whining noises
  • Transmission overheating
  • Dark, burnt-smelling fluid

Ignoring these warning signs can lead to serious damage and very expensive repairs.

How Often Should You Change It?

  • Most vehicles need a transmission fluid change every 30,000–60,000 miles.
  • Check your owner’s manual for your specific recommendation.
  • Heavy towing, stop-and-go traffic, or frequent highway driving may require more frequent changes.

Why Preventative Maintenance Saves Money

A fluid change is a relatively inexpensive service compared to a transmission rebuild or replacement, which can cost thousands. Regular fluid maintenance keeps your transmission running longer, smoother, and more efficiently.
