The Key Symptoms That Your Gearbox Is About to Breakdown

by | Jul 24, 2022 | Tips

Should you want to save yourself from having to pay for expensive repairs, pay attention to those little indications that your automobile is experiencing issues. And the transmission is among the most costly parts in your automobile, so you don’t want to mess it up and don’t want to be looking for costly spare part from our network of Audi breakers in the near future! Vigilance is essential since gearbox problems may be very serious. If you’re not sure what to look for, we’ve put up a basic checklist to help you identify the most common symptoms of gearbox trouble.

Dashboard Indicators

The dashboard’s engine lights turn on for a purpose. A higher operating temperature for the fluid in your transmission will be indicated by the transmission temperature light, so keep an eye out for it. Make sure your transmission fluid and coolant are at their appropriate levels by doing these two simple checks. Possibly though this light could not indicate a transmission issue and might even be unrelated to the gearbox, it is crucial to have any possible issues inspected by a qualified technician.

Low Levels and Fluid Leakage

This might be the most obvious symptom on our list. The only thing that has to be done is to check for leaks below the automobile by putting a few used pieces of cardboard underneath it. You’re searching for the distinctive red color and somewhat sweet-smelling scent of transmission fluid. Any indication that there is transmission fluid beneath the car—which should not fluctuate as motor oil does—indicates a leak.

Before removing the dipstick without shutting off the engine, briefly run your automobile in neutral to do the fluid tests. Highlight the color by rubbing a bit of the fluid between your fingers and thumbs or by drizzling it on a piece of white toilet paper or paper towel.

The dipstick should be inserted, cleaned, and then reinserted to check the levels. Now take it out of the envelope, and search for a mark in the space between the full line and the add line. If the fluid level falls below the add line, the user is instructed to top it up with additional. To ensure you use the correct fluid and add the appropriate quantity, see your owner’s handbook. If you are doubtful, gradually increase the amount and recheck the levels.

There is a good likelihood you have a leaky system if fluid levels are lower than expected:

  • Symptoms of a blocked filter or a loose plug
  • worn gaskets or seals
  • worn axles in a car with front-wheel drive
  • Insufficient support for the engine and gearbox
  • defective bell housing
  • transmission pan leak or a loose pan
  • Out of balance drive shaft
  • odors and smells

It may be time to replace the transmission fluid if you notice faint odors or burning odors that leave your car with a sweet and sour scent. It’s time for a replacement if the fluid isn’t maintaining the system adequately lubricated so that the device doesn’t self-extinguish. If the transmission fluid has a burned smell when you inspect it, your gearbox may be close to failure. To prevent costly damage, get it examined by a specialist as soon as possible.

Funny Sounds

There, everyone has been. Silence in the vehicle as the driver instructs the passengers to keep an eye out for a banging sound as they shift gears. However, if the automobile makes banging or clanking sounds when it shifts into neutral, this might be an indication of loose clutch gears and components. The likelihood of damage is higher the louder the noises, the looser the components.

Watch out for whistling and clicking sounds, since these might indicate that your gearbox’s bearings are wearing out and that you should consider getting a replacement. When changing gears, sudden, jarring grinding noises might indicate that the synchronizers or clutch are faulty or worn out.

Instead of a smooth shift, automatic transmissions cause you to feel the gear changes. However, there is a strong probability that you will also hear a whining, buzzing, or humming noise. The torque converter can have an issue with this.

Strange Behavior

You are familiar with how your automobile behaves. If the gear begins shifting randomly, such as while you’re driving down the highway and your automatic gearbox goes into neutral or your manual gearbox moves into a different gear, there is an issue with the shifting. A whine from the engine or an accompanying pitch change is another warning indication to listen for.

Another sign that shouldn’t be ignored is delayed gearbox engagement. Is there a little delay before your automobile shifts into drive and moves forward? If the clutch is at the biting point and you have previously depressed it, yet it takes some time to move, the part is likely to fail soon.

And lastly

Even for skilled technicians, diagnosing faults with your automobile isn’t always simple. Keep in mind that you should consult a mechanic immediately away if anything doesn’t seem quite right rather than waiting until it becomes a pricey issue. You should get your automobile into the garage as soon as there is even the slightest sign that the gears aren’t functioning correctly. Before further damage develops or you have a malfunction on the open road, be sure to get your automobile inspected.
