Knowing how to check your transmission fluid regularly helps prevent maintenance issues before they become a more serious and expensive problem. The transmission propels your vehicle forward, which is why it’s essential to stay up-to-date on routine maintenance services like checking the transmission fluid. If you’re unsure how to measure the transmission fluid level in your new or used Mercedes-Benz vehicle, we can help! Learn how to check the transmission fluid in a few easy steps.

Checking Transmission Fluid: Step-by-Step Guide 

Follow these steps:

  1. Turn the engine and let it run for a few minutes since it needs to be warmed up to properly check the level. Park your car and open the hood.
  2. Find the transmission fluid dipstick. Refer to your vehicle’s owner’s manual if you have trouble locating it.
  3. Remove the dipstick and touch the fluid by moving it around between your thumb and forefinger. The fluid should be almost clear with a pink hue. If it looks dirty or gives off a burnt smell, take it to our service center near Cincinnati for a replacement.
  4. Wipe off the dipstick with a rag. Then insert it back into the vehicle. Pull it out again and check the level. If it’s under the “Full” marking, add more fluid.
  5. Use a funnel to bring the fluid level up to the correct spot. Be sure not to overfill it.

Feel free to contact our service department if you run into any issues or have questions.

Checking the Fluid in a Sealed Transmission 

If you don’t see the dipstick under the hood, there’s a chance that your car is equipped with a sealed transmission. What is a sealed transmission? Sealed means that there is not a dipstick to measure the transmission fluid level. If your car has a sealed transmission, don’t attempt to check its fluid level because it can get damaged. Our factory-trained and certified service team can check the transmission fluid level when you bring it to our service center near Monroe. 

When to Check the Fluid in a Sealed Transmission 

The sealed transmission is meant to limit the amount of wasted transmission fluid, which saves you money in the long run. However, problems can still occur, and the fluid will need to get replaced. Watch out for these red flags, which indicates that there’s an issue with your sealed transmission:

  • You can hear strange noises when the gears change. 
  • The gears hesitate before changing. 
  • During acceleration, there’s a noticeable delay when the gears shift.

How Often Do You Check Your Transmission Fluid?

Transmission fluid levels should be checked monthly. This includes inspecting your transmission fluid, power steering fluid, and engine oil. Refer to your vehicle’s owner’s manual for specific maintenance schedules.

Transmission Fluid Basics

Your transmission is a complex part of your vehicle, so before checking the fluid, read these tips:

  • Not all transmission fluid is the same. There are different types for more recent models, manual transmissions, and automatic transmissions. Your owner’s manual will recommend the type of transmission fluid. 
  • Checking the fluid on a manual transmission usually requires a jack to access a plug located under the car. For most drivers, a visit to our service center near Oxford is a more convenient option.
  • If your vehicle hesitates before shifting gears, it could be due to having low transmission fluid. Check the fluid level, but if that’s fine, schedule a service appointment with us.
  • Transmission fluid should be replaced every 50,000 to 100,000 miles. However, the actual amount varies based on your driving habits, the type of transmission, and other factors. Check your vehicle’s owner’s manual for specific replacement intervals.
