When it comes to maintaining your 2008 BMW 328i, one crucial aspect that often gets overlooked is the transmission fluid. Properly maintaining the transmission fluid can help ensure smooth gear shifts and extend the lifespan of your transmission. In this article, we will discuss the transmission fluid capacity for the 2008 BMW 328i, so you can keep your car running smoothly.

Transmission Fluid Capacity and Type

Before we dive into the details, let’s get straight to the point. The transmission fluid capacity for the 2008 BMW 328i is approximately 9.5 quarts or 9 liters. It’s important to note that this capacity may vary slightly depending on the specific model and transmission type, so always consult your owner’s manual or a trusted mechanic for accurate information.

Now, let’s talk about the type of transmission fluid you should use. BMW recommends using their own branded transmission fluid, which is known as BMW ATF 3+ or BMW ATF 4+. These fluids are specially formulated to meet the requirements of your BMW’s transmission and provide optimal performance.

Using the right type of transmission fluid is crucial to maintain the proper lubrication and cooling properties within your transmission. It helps to reduce friction, prevent wear and tear, and ensure smooth gear shifts. So, don’t cut corners by using generic or incompatible fluids that might cause damage to your transmission.

How to Check and Add Transmission Fluid

Checking and adding transmission fluid to your 2008 BMW 328i is a relatively simple process. However, it’s important to exercise caution and follow the correct steps to avoid any mishaps. Here’s a step-by-step guide to help you:

  1. Park your vehicle on a level surface and engage the parking brake.
  2. Locate the transmission fluid dipstick. It is usually labeled and can be found near the back of the engine bay.
  3. Remove the dipstick and wipe it clean with a lint-free cloth or paper towel.
  4. Reinsert the dipstick fully and then remove it again to check the fluid level. The dipstick will have markings indicating the minimum and maximum levels.
  5. If the fluid level is below the minimum mark, you will need to add transmission fluid. Use a funnel to pour the fluid into the transmission through the dipstick tube. Be careful not to overfill.
  6. Recheck the fluid level using the dipstick and add more fluid if necessary.
  7. Once the fluid level is within the acceptable range, securely reinsert the dipstick and ensure it is properly seated.

Remember, always use caution when working with hot fluids and ensure the engine is off before checking or adding transmission fluid. If you are unsure or uncomfortable performing this task yourself, it’s best to consult a professional mechanic.


Now that you know the transmission fluid capacity for your 2008 BMW 328i and the importance of using the correct type of fluid, you can take the necessary steps to maintain your transmission properly. Regularly checking and adding fluid when needed will help ensure smooth gear shifts and prolong the life of your transmission. Don’t neglect this essential aspect of car maintenance, as it can save you from costly repairs down the road. Keep your BMW running smoothly and enjoy the ultimate driving experience!
