In this article, we will discuss the transmission fluid capacity for the 2016 GMC Sierra and provide you with all the necessary information you need to keep your truck running smoothly.

Transmission Fluid Capacity and Type

Before we dive into the specifics, let’s take a look at the transmission fluid capacity and type for the 2016 GMC Sierra:

Now that you know the fluid capacity and type, let’s discuss why it is important to maintain the correct fluid level in your transmission.

Why Transmission Fluid Capacity Matters

Your transmission relies on the proper amount of fluid to function efficiently. If the fluid level is too low, it can lead to increased friction and heat, which can cause damage to the transmission components. On the other hand, if the fluid level is too high, it can lead to foaming and fluid leakage, which can also result in transmission problems.

By maintaining the correct fluid capacity, you can ensure that your transmission operates smoothly, shifts gears properly, and avoids unnecessary wear and tear. Regularly checking and topping up the transmission fluid can help prevent costly repairs down the line.

How to Check and Add Transmission Fluid

Checking and adding transmission fluid to your 2016 GMC Sierra is a relatively simple process. However, it is important to follow the manufacturer’s guidelines and take necessary safety precautions. Here are the steps to check and add transmission fluid:

  1. Park your truck on a level surface and engage the parking brake.
  2. Locate the transmission dipstick, which is usually labeled and located near the back of the engine compartment.
  3. With the engine running and the transmission in “Park,” remove the dipstick and wipe it clean with a lint-free cloth.
  4. Reinsert the dipstick fully and then 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, add the appropriate transmission fluid gradually, using a funnel to avoid spills.
  6. Recheck the fluid level using the dipstick and add more fluid if necessary. Be careful not to overfill.
  7. Replace the dipstick securely and close the hood.

Remember to consult your owner’s manual for any specific instructions or precautions related to checking and adding transmission fluid for your 2016 GMC Sierra.


Ensuring that your 2016 GMC Sierra has the correct transmission fluid capacity is essential for maintaining its performance and longevity. By following the guidelines provided in this article and regularly checking and topping up the transmission fluid, you can keep your truck running smoothly and avoid costly repairs.
