As you can see, the manual transmission in your 2012 Chevy Sonic requires approximately 2.4 quarts or 2.3 liters of transmission fluid. It’s important not to overfill or underfill the transmission, as it can lead to performance issues or damage.

Choosing the Right Transmission Fluid

Now that you know the fluid capacity, let’s talk about the type of transmission fluid you should use. For the 2012 Chevy Sonic with a manual transmission, General Motors recommends using DEXRON-VI Automatic Transmission Fluid (ATF). This type of fluid is specifically designed to meet the requirements of your transmission and provides excellent lubrication and protection.

When purchasing transmission fluid, make sure to check the label and ensure it meets the DEXRON-VI specification. Using the wrong type of fluid can cause damage to your transmission and void any warranty you may have.

Fluid Change Procedure

Changing the transmission fluid in your Chevy Sonic is a relatively straightforward process. However, it’s important to follow the proper safety precautions and consult your vehicle’s owner’s manual for detailed instructions. Here’s a general overview of the fluid change procedure:

  1. Ensure your vehicle is parked on a level surface and the engine is turned off.
  2. Locate the transmission fluid drain plug underneath your vehicle. Use a wrench to remove the plug and drain the old fluid into a suitable container.
  3. Once the fluid has completely drained, reinstall the drain plug and tighten it securely.
  4. Locate the transmission fluid fill plug, which is usually located on the side of the transmission. Remove the plug.
  5. Using a funnel, slowly pour the recommended amount of DEXRON-VI ATF into the fill hole.
  6. Replace the fill plug and tighten it securely.
  7. Start your vehicle and allow it to idle for a few minutes. Check for any leaks around the transmission.
  8. Finally, shift through all the gears to ensure proper fluid circulation.

Remember, it’s always best to consult your vehicle’s owner’s manual for specific instructions and safety precautions before attempting any maintenance procedures.


Maintaining the proper fluid capacity and using the correct type of transmission fluid is essential for the longevity and performance of your 2012 Chevy Sonic’s manual transmission. By following the guidelines provided in this article, you can ensure that your transmission stays in top shape for years to come.
