A gearbox, or a transmission, is a complex mechanism that propels power from the engine to the wheels of a vehicle. When a gearbox fails, it can be dangerous as it can damage other auto parts in the vehicle and cause serious accidents when it finally breaks down. This is why it is important to be aware of the failing indicators of a gearbox.
Mercedes is well-known for producing high-quality luxury vehicles that can last long with proper care and maintenance. However, improper handling of vehicles may cause damage to the gearbox. To know when a Mercedes gearbox is failing, we’ve compiled a list of key signs to look out for below.
Importance of Maintaining Your Mercedes Gearbox
The gearbox is the second most vital mechanism to make your vehicle perform smoothly on the road. With the engine being the most important mechanism, the gearbox helps propel power from it to the wheels. Seeing how critical the gearbox is in making a vehicle function, maintaining a gearbox is important.
Most Mercedes users take great care of their vehicles, but it is not enough to be immune to damage. Exposure to harsh weather conditions, road grime, or rapidly switching between gears can cause the gearbox to overheat and lead to failure.
However, your Mercedes gearbox will work well and smoothly if properly maintained. Repairing or replacing a gearbox can be expensive, which can be higher for a Mercedes owner. Be sure to look for subtle and critical signs of gearbox failure to save money and prevent major issues.
5 Signs That Your Mercedes Gearbox is Failing
A Mercedes gearbox can run smoothly without maintenance even after 3 to 5 years of purchase. However, maintenance is still a must to detect any damage earlier to avoid more costly repairs in the future.
Factors like improper vehicle handling and bad driving habits can lead to the gearbox malfunctioning. Here are 5 signs to look out for that signal when your Mercedes gearbox is failing.
Listen to the noises your vehicle makes when you drive it. As rapidly changing gears can damage your gearbox, it is likely that your transmission is failing when the action makes grinding or rumbling noises. Strange noises like squeaking, buzzing, whining, and humming indicate a transmission problem.
Do not ignore these strange noises emitting from your car as it indicates an internal issue. When this happens, schedule a maintenance appointment to get it checked before it gets worse.
Delayed or Rough Shifting
Whether it’s an automatic or a manual transmission vehicle, delayed or rough shifting is a warning sign of a failing transmission. It signals a transmission problem due to insufficient transmission fluid or lack of maintenance.
Driving any vehicle that shifts gears unexpectedly is dangerous and poses a risk to you and everyone else on the road. When accelerating, your gears might take longer to upshift. When this happens, it is time to schedule routine maintenance.
Mercedes is equipped with a transmission trouble indicator that will appear on the vehicle’s control panel. When the wrench icon is illuminated, it warns you of a problem with its transmission.
Ignoring a clear indicator of transmission troubles only asks for problems as they worsen. Take the warning lights as a last-ditch effort of your vehicle calling for help. Immediately addressing the issue is crucial as there will be higher expenditures when the problems worsen, especially for Mercedes vehicles.
Have you encountered any reddish or brown leaks pooling under your vehicle? If this is the case, your transmission fluid is likely leaking. Transmission fluid ensures the gearbox functions appropriately and smoothly as it lubricates and cools the moving parts.
When a leak happens, the gearbox overheats, which signals increased friction from improper handling of the vehicle. Your vehicle cannot perform smoothly with insufficient transmission fluid that aids in cooling and lubricating the gearbox.
Slipping gears is a clear indication of transmission failure. It is a result of wear and tear from insufficient transmission fluid. Over time, gears can wear out from the gearbox overheating as it lacks transmission fluid to cool it down.
As this results from wear and tear, it causes the gears not to engage correctly. It is dangerous, so getting your transmission checked is crucial to avoid catastrophic problems on the road due to malfunctioning gears.
Significance of Prompt Diagnosis and Repair
Prompt diagnosis of gearbox failure helps in saving money, time, and effort. Repairing gearboxes in any car can be costly, which especially applies to Mercedes.
With prompt diagnosis, the gearbox can be repaired before becoming a major issue. Some repairs may only look at the gearbox, the transmission fluid, filter replacement, lubrication, or fitting. If you choose to drag on the issue, you might not just need a repair; a replacement might be required for your gearbox.
To avoid this from happening, ensure that you are aware of the warning signals from your vehicle, whether it be subtle or not. By taking care of the warning signs, you save money, time, and effort in the long run.
