As a car owner, you know that regular maintenance is essential for keeping your vehicle in good working condition. One of the most critical components of your car is its transmission, and the fluid that keeps it lubricated and functioning correctly. In this ultimate guide to transmission fluid, we’ll answer the question of how often you should change it.

What is Transmission Fluid?

Transmission fluid is a type of oil that lubricates the moving parts of your vehicle’s transmission, keeping it running smoothly. Without transmission fluid, your transmission would overheat, wear out faster, and eventually break down. Most cars have an automatic transmission, which requires transmission fluid to operate correctly.

How Often Should You Change Your Transmission Fluid?

So, how often should you change your transmission fluid? The answer varies depending on several factors, such as your car’s make and model, driving habits, and transmission type. In general, most car manufacturers recommend changing the transmission fluid every 30,000 to 60,000 miles. However, some vehicles may require more frequent changes, such as every 15,000 miles.

If you frequently drive in stop-and-go traffic or tow heavy loads, your transmission may require more frequent fluid changes. Additionally, if you notice any issues with your transmission, such as slipping gears or delayed shifting, it’s a sign that you should have your transmission fluid checked and possibly changed.

How to Check Your Transmission Fluid

Checking your transmission fluid level regularly is an essential part of maintaining your vehicle’s transmission. To check your transmission fluid, follow these steps:

  1. Park your car on a level surface and turn off the engine.
  2. Locate the transmission dipstick (usually near the back of the engine bay).
  3. Pull out the dipstick and wipe it clean with a rag.
  4. Insert the dipstick back into the transmission and pull it out again.
  5. Check the fluid level on the dipstick. The fluid should be within the “full” or “max” marks.

If the fluid level is low, add more fluid using a funnel. Be sure to use the correct type of transmission fluid specified in your owner’s manual.


Regularly changing your transmission fluid is essential for keeping your car running smoothly and avoiding costly repairs.
