2008 Cobalt Transmission Fluid Capacity

When it comes to taking care of your 2008 Cobalt, one important aspect is ensuring that the transmission fluid is at the right level. Knowing the transmission fluid capacity is crucial for maintaining the optimal performance of your vehicle. In this article, we will provide you with the necessary information about the transmission fluid capacity for your 2008 Cobalt, so you can keep your car running smoothly.

Transmission Fluid Capacity and Type

Before we dive into the specifics, let’s get straight to the point. The transmission fluid capacity for a 2008 Cobalt is approximately 7.4 quarts or 7 liters. It’s always a good idea to have a bit extra on hand, just in case.

Now, let’s talk about the type of transmission fluid you should use. For your 2008 Cobalt, General Motors recommends using DEXRON-III automatic transmission fluid. It’s important to stick to this recommendation to ensure proper lubrication and performance of your transmission.

How to Check and Add Transmission Fluid

Checking and adding transmission fluid is a relatively simple process, but it’s crucial to follow the correct steps. Here’s a step-by-step guide to help you:

  1. Park your Cobalt on a level surface and engage the parking brake.
  2. Locate the transmission fluid dipstick, which is usually labeled and has a bright handle.
  3. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully into the transmission and then pull it out again.
  5. Check the fluid level on the dipstick. It should be within the “Full” or “Hot” range.
  6. If the fluid level is low, you can add transmission fluid through the dipstick tube using a funnel. Add small amounts at a time and recheck the level until it reaches the appropriate range.
  7. Remember not to overfill the transmission, as it can lead to damage.
  8. Once you’re done, securely reinsert the dipstick and make sure it’s properly seated.

It’s important to note that if you notice a significant decrease in transmission fluid level or if the fluid appears to be discolored or has a burnt smell, it may indicate a potential issue with your transmission. In such cases, it’s best to consult a professional mechanic for further inspection and diagnosis.


Now that you know the transmission fluid capacity for your 2008 Cobalt, you can confidently maintain the proper fluid level and keep your transmission in top shape. Remember to use DEXRON-III automatic transmission fluid and follow the correct steps when checking and adding fluid. Regular maintenance is key to ensuring the longevity and performance of your vehicle, so don’t neglect this important aspect of car care.

Keep your Cobalt running smoothly and enjoy the road ahead!
