When it comes to maintaining your 2015 GMC Acadia, one important aspect to consider is the transmission fluid. Properly maintaining the transmission fluid can help ensure smooth shifting and extend the lifespan of your vehicle’s transmission. In this article, we will discuss the transmission fluid capacity for the 2015 GMC Acadia, as well as the type of fluid required.

Transmission Fluid Capacity

Knowing the transmission fluid capacity of your vehicle is essential for proper maintenance. The 2015 GMC Acadia has a transmission fluid capacity of approximately 11.1 quarts or 10.5 liters. It is important to note that this capacity may vary slightly depending on the specific model and engine configuration of your Acadia.

Type of Transmission Fluid

Now that you know the transmission fluid capacity, let’s talk about the type of fluid required. The 2015 GMC Acadia requires Dexron VI automatic transmission fluid. This type of fluid is specifically formulated for use in General Motors vehicles and provides excellent lubrication and protection for the transmission components.

It is crucial to use the recommended Dexron VI fluid to ensure optimal performance and avoid potential damage to your Acadia’s transmission. Using the wrong type of fluid can lead to shifting issues, overheating, and even transmission failure.

How to Check and Add Transmission Fluid

If you suspect that your Acadia’s transmission fluid is low, it is important to check and add fluid as needed. Here are the steps to do so:

  1. Park your Acadia on a level surface and engage the parking brake.
  2. Locate the transmission fluid dipstick, which is usually labeled and located near the back of the engine bay.
  3. With the engine running and the transmission in “Park,” remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and remove it again to check the fluid level. The dipstick will have markings indicating the proper fluid level range.
  5. If the fluid level is below the recommended range, carefully add small amounts of Dexron VI fluid through the dipstick tube. Be cautious not to overfill, as this can also cause transmission issues.
  6. Recheck the fluid level using the dipstick and add more fluid if necessary.
  7. Once the fluid level is within the recommended range, securely reinsert the dipstick and ensure it is properly seated.

Remember to always follow the manufacturer’s guidelines and refer to your vehicle’s owner’s manual for specific instructions and precautions.


Maintaining the proper transmission fluid level in your 2015 GMC Acadia is essential for smooth shifting and the longevity of your vehicle’s transmission. By knowing the transmission fluid capacity and using the recommended Dexron VI fluid, you can ensure optimal performance and avoid potential transmission issues. Remember to check the fluid level regularly and add fluid as needed, following the proper procedures outlined in your owner’s manual. Keep your Acadia running smoothly and enjoy the journey ahead!
