Mercedes Transmission Fluid
Keeping your Mercedes-Benz in top condition requires regular servicing and maintenance.
One of the most important areas of maintenance is checking the transmission fluid. Your vehicle’s transmission fluid keeps your transmission system cool and lubricated.
However, most Mercedes-Benz owners don’t know how to check the transmission fluid and are unsure what to do when the fluid is contaminated or low.
In this blog, you’ll discover everything you need to know about checking your Mercedes-Benz transmission fluid.
We’ll discuss:
- The importance of checking the fluid.
- Where you can find the dipstick.
- The different types of transmission fluids used.
- How to know if the fluid is contaminated or low.
- How often you need to check it.
We’ll even tell you what’s involved in a fluid change and whether you should replace the transmission fluid yourself or leave it to our Mercedes-Benz experts at Fergies.
We’ll go through everything you need to know about general transmission fluid maintenance tips to keep your vehicle running like new.
With that said, let’s get into it…
Locating and Checking Your Mercedes-Benz Transmission Fluid

To check your transmission fluid level, you’ll first need to locate the dipstick.
You can usually find the dipstick towards the back of your Mercedes-Benz engine compartment. The handle is usually bright red, but this may vary depending on your Mercedes model.
Checking your transmission fluid level is straightforward once you have identified the dipstick. To do so, follow these steps:
- Park your Mercedes on a level surface and put the brake on.
- Start the engine and let it idle for a few minutes to warm up the transmission fluid.
- Switch off the engine.
- Locate the transmission fluid dipstick.
- Carefully remove the dipstick and wipe it clean with a microfibre cloth or paper towel.
- Reinsert the dipstick fully and then remove it again.
- Check the fluid level on the dipstick. There may be “minimum” and “maximum” marks or indicators. The fluid level should be between these two marks.
- If the fluid level is low, you will need to add the appropriate transmission fluid and recheck the fluid level using the dipstick until it reaches the proper range.
- Once the fluid level is correct, securely reinsert the dipstick back into its place.
When your vehicle’s fluid level is below the minimum mark, you need to replace the fluid immediately to prevent any damage to your engine.
On the other hand, if the transmission fluid level exceeds the maximum mark, the fluid needs to be drained and refilled. Failing to do so can also cause severe engine damage through issues such as fluid foaming, fluid leakage, transmission slippage, and increased heat.
At Fergies, we recommend checking your transmission fluid level regularly to ensure your Mercedes-Benz runs smoothly while preventing costly future repair bills.

Know Which Transmission Fluid is Right for Your Mercedes
It’s important to know exactly what transmission fluid your Mercedes needs. All Mercedes-Benz vehicles have their own transmission fluid requirements. This will be dependent on the year and model of your vehicle.
Using the right transmission fluid for your Mercedes ensures your vehicle performs at its best while preventing potential engine damage.
Your owner’s manual will be able to tell you what transmission fluid your Mercedes will need, but if you’re still unsure our Mercedes-Benz experts here at Fergies will be able to help. We only ever use high-quality transmission fluid, specific to your Mercedes model and year.

Signs of Low or Contaminated Transmission Fluid
Your vehicle’s transmission system is a complex combination of mechanical and electrical components that work together in order for the engine to work. Without it, you wouldn’t be able to drive your Mercedes-Benz.
The gearbox, clutch, sensors, fluid, electronic control unit etc., all form part of the transmission system.
If your transmission fluid becomes contaminated, it can cause several issues with your transmission. Such as:
Clutch Slippage – Contaminated fluid can cause your clutch packs to slip, leading to loss of power, poor gear changes and increased heat build-up. If left, it’ll cause the clutch to burn out and a replacement will be required.
Increased Wear – Contaminated transmission fluid can cause wear on the gears, bearings, and other moving parts. This might lead to a premature failure of these components and will require costly repairs.
Overheating – Contaminated fluid can also cause your vehicle’s transmission to overheat, as it’s unable to cool down correctly and can’t lubricate the system’s components. If left, it can cause damage to the seals, gaskets, and other areas of your transmission.

How Often Should Transmission Fluid be Checked?
Mercedes-Benz recommends checking the transmission fluid level in their vehicles regularly as part of routine maintenance. The exact frequency may vary depending on the specific model and year of your Mercedes, so it’s best to consult your owner’s manual for the manufacturer’s recommendations.
As a general guideline, at Fergies we recommend checking your transmission fluid level every six months. However, if you notice any signs of transmission issues such as slipping gears or fluid leaks, it’s important to have the transmission fluid inspected at a reputable garage right away.
Ultimately, staying up to date with your vehicle’s maintenance schedule, including regular checks of the transmission fluid, will help ensure the best performance and longevity of your Mercedes.
