Signs that Something May Be Wrong with Your Transmission

5 Signs Your Mercedes-Benz May Need Transmission Service

From the latest sophisticated dual-clutch transmissions on powerful Mercedes-AMG® sports cars to durable automatic and manual transmissions on older Mercedes-Benz classics, the transmission is one of the most critical components of your vehicle’s drivetrain. Let us help you care for it here at Mercedes-Benz of Temecula. An official Mercedes-authorized service center is the only place to get the expert maintenance, quality OEM components and friendly customer service Mercedes-Benz owners demand. Whether your Mercedes vehicle is new or old, whether it’s a modern classic or a classic-classic, trust the professionals at Mercedes-Benz of Temecula.

Below, we’ll go over five common signs that your vehicle is experiencing transmission trouble.

4. New Noises When Shifting

When it’s working properly, you shouldn’t hear the transmission when it shifts into a new gear — you should just hear the change in the note the engine sings. But, if you can detect an audible “clunk” when shifting gears, the transmission gears themselves may have become worn. Instead of smoothly sliding from one gear to another, worn gears may make a loud noise when you shift. To ensure your transmission continues to serve you well, have it inspected by a trained Mercedes-Benz technician if you detect some new noises.

3. Unusual Burning Smell

There are all sorts of reasons you might smell burning coming from your car — but all of them need immediate attention. If it isn’t rubber burning on your tires, a fuel system leak or an exhaust system problem causing this burning smell, it could be excessive heat and friction building up in the transmission. This is likely caused by an insufficient transmission fluid level. You may want to check beneath your vehicle for fluid leaks. A leaking transmission will eventually cause the gears to grind and create excess friction from lack of lubrication, which can cause a burning smell in the cabin.

2. Vehicle Won’t Go Into Gear, Or Stay In Gear

If your vehicle with automatic transmission simply won’t go into Drive or stalls when shifting into Reverse, you likely need transmission service. This problem can be caused by severely worn transmission fluid, or a transmission that needs a flush and fill service. And if your vehicle has a manual transmission and won’t go into a particular gear or slips out of a particular gear, there may be issues with your vehicle’s manual gearbox.

If your car won’t stay in gear no matter how hard you try, it may not be safe to operate. Give our service center a call and we can help bring your vehicle safely to our service center.

1. Check Engine Light Is Illuminated

Don’t be misled by the name. The “Check Engine” warning light doesn’t always indicate engine problems specifically. Other systems including the intake, exhaust and the transmission are monitored by advanced sensors. These sensors feed their data back to the engine’s central computer, or ECU. If something unusual has been detected by the sensors, the check engine light may come on so you can have a technician inspect your vehicle and make any needed adjustments or repairs.

If the transmission fluid level or temperature are out of spec, slippage is detected in the transmission or the sensors themselves aren’t working as intended, the only sign you may notice could be the Check Engine light turning on. At least, at first. Driving your vehicle for too long without getting the Check Engine light diagnosed can cause problems to worsen over time — and could lead to a more costly repair.

Instead, speak with one of the factory-trained Mercedes-Benz experts in our service center as soon as your Check Engine light comes on. We’ll help keep your Mercedes-Benz running like new. Just give us a call, or schedule your maintenance appointment right here on our site.
