Your Car Lacks Power

Does the engine run fine but your car appears not to have power? If so, one of the main reasons for this could be that there is a problem with the transmission system. Sometimes, it could also be due to dragging brakes as a result of a faulty caliper or brake hose.

Missing Gears or Delayed Shifts

A tell-tale sign of a poor transmission system is that your Mercedes takes a bit longer than usual before it goes into gear. If you notice this unusual delay in gear shifting, you probably need to have your car’s automatic transmission system checked. The primary cause of this is a low level of transmission fluid due to leaking.

Also, it could be that the transmission fluid is contaminated due to lack of maintenance. At first, this may not seem like a big problem. However, if it is not checked, it could easily lead to overheating which runs the risk of damaging internal transmission parts. Engine problems could also be the reason for delayed shifts. These problems often prevent the computer system of your car from permitting seamless shifting.  

Transmission Fluid is Leaking

Leaking of transmission fluid can cause it to reduce in level, something that can cause several other problems. Fortunately, you don’t need to be a professional mechanic to tell that you leak your transmission. You just need to inspect the place you normally park your Mercedes for red fluid. The presence of this fluid is a surefire way to confirm a leakage.

In most cases, transmission fluid leaks are from the cooler lines, a gasket, or seal. If the fluid happens to leak on a surface like a hot pipe, things could become much worse. Use a dipstick to check that the fluid level is right and also that it’s in perfect condition. It is, however, worth noting that the transmission fluid is not always red. Also, in some instances, you may need certain specialized tools to test the transmission fluid level and not just a dipstick.

Clicking, Buzzing or Humming Noise

When you notice any of these noises from the transmission when driving, the first thing could be bad bearings. The noises could also point to planetary gear damage. The buzzing sound is mostly because of a bad seal or low transmission.

Burning Smell

Yet another probable cause of a malfunctioned transmission system is a burning smell. It usually points to a leak of transmission fluid.

Catching this smell as early as possible is critical as it will help you save your automatic transmission system from being damaged further. Consult your car owner’s manual to learn how to check transmission fluid levels and conditions using the included dipstick.


Your car’s transmission system is one of the most expensive components of your vehicle. Replacing it often costs more than installing a new engine. That’s why you don’t want it to malfunction.

The good news is that it’s easy to spot the signs of a troubled transmission system early on and fix it before it gets damaged further. Always be keen while driving and pay attention to the transmission fluid level and condition. Also, watch out for any burning smells.
