It’s beneficial for drivers to know how to regularly change their transmission fluid, as it helps prevent any small maintenance issues from turning into serious, more expensive ones. Since your transmission is what moves your vehicle forward, it’s essential to stay up-to-date on routine maintenance. Wondering how to measure the transmission fluid in your new Mercedes-Benz or used vehicle? We have you covered in this handy guide from the service experts at Mercedes-Benz of Cincinnati.

A Guide to Checking Transmission Fluid 

To check the transmission fluid, follow these easy steps: 

  1. Turn the engine and let it run for a few minutes before doing anything, as the engine needs to be warmed up to properly check the level. Park your vehicle and open the hood.
  2. Find the transmission fluid dipstick. If you’re having trouble locating it, refer to your vehicle’s owner’s manual. 
  3. Remove the dipstick and touch the fluid by moving it between your thumb and forefinger. The fluid should be just about clear with a pink hue. If you notice that it’s dirty or gives off a burnt smell, it’s essential to bring it to our service center near Blue Ash for a replacement.
  4. Use a rag to wipe off the dipstick. Insert it back into the vehicle, and pull it out again to check the fluid level. If it’s under the “full” marking, more fluid is needed.
  5. Use a funnel to bring the fluid level up to the right spot, without overfilling it.

Don’t hesitate to contact our service department if you have any questions or run into any problems.

Sealed Transmission: Checking the Fluid 

Don’t see a dipstick? Your vehicle may have a sealed transmission, which means no dipstick allows you to measure the transmission fluid level. If your vehicle has this, don’t attempt to check the fluid level because it may damage it as a result. Our factory-trained and certified service team will inspect the transmission fluid for you.

When Should I Check the Fluid in a Sealed Transmission?

The reason for a sealed transmission is to limit how much transmission fluid is wasted, which saves you money. However, issues can still happen, and your transmission fluid will need to get replaced. Watch out for these red flags indicating there are any issues 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?

Montgomery drivers should make sure they’re checking their fluid levels monthly. This includes inspecting your transmission fluid, power steering fluid, and engine oil. Refer to your owner’s manual for a more specific maintenance schedule.

Transmission Fluid Basics

Your transmission is a complex part of your vehicle. Before checking your transmission fluid, explore these handy tips:

  • Not all transmission fluid is the same, due to the different types for recent models and manual and automatic transmissions. 
  • Checking the fluid on a manual transmission typically requires a jack to access a plug under the car. For many drivers, a visit to our service center near Sharonville is more convenient.
  • If your vehicle hesitates before shifting gears, it can be due to low transmission fluid. However, it could be a sign of a more serious problem. Check the fluid level first, but if it’s fine, then schedule service with us today.
  • It’s recommended to replace your transmission fluid every 50,000 to 100,000 miles. This number can vary depending on your driving habits, type of transmission, and additional factors.
