What are the symptoms of a bad

gearbox/transmission?

Some tell-tale signs you may need to look at your car's transmission...

Whining and Clunking

This may seem fairly obvious, but those are often the symptoms we ignore the most. When your car starts making noises it shouldn’t be making, it’s time to get it checked out. You’ll probably hear a humming or buzzing coming from your transmission. When this happens, don’t wait to bring it in. Fix it as soon as possible before any further damage occurs.

Lack of Response

Your transmission was designed so that you can switch gears instantaneously. So when there is a delayed response and it doesn’t immediately do what you want it to, you guessed it. It’s time for a checkup.

Burning Smell

The smell of something burning is never a good sign when it’s coming from your car. The cause could be any number of things, but it’s most commonly the overheating of the transmission fluid. Don’t panic when this happens, just get it checked out as soon as possible.

Leaking Fluid

Fluid, where it shouldn’t be, is one of the easiest symptoms to spot. The best way to find where the leak is coming from is to lay down a few pieces of cardboard when the car is parked. Then slide out the pieces to see just where your car is leaking. Be sure to share this information with the mechanic or service professional when you take it in to be resolved.

Grinding Gears

This symptom manifests itself differently for manual and automatic transmissions. For manual transmissions, when you change gears and you hear or feel a sense of grinding; it may mean that you have just worn out the clutch and you need to replace it. But it can also mean that one of the transmission’s synchronizers is worn out and damaged. For automatic transmissions, a rough shift rather than an unnoticeable one could be caused by a few things. Take it into a professional to diagnose.

What are the signs of a bad clutch?

The clutch is a hugely important part of your vehicle - without it, you'd be unable to change between gears. Like many of your car's components, it is possible your clutch may wear out over time.

Find out more about what your Porsche’s clutch does below, and what symptoms to look out for if you think yours might be due for replacement.

There are many factors that contribute to how long your clutch is likely to last. Clutches are designed to last anywhere between 50,000 and 100,000 miles or maybe even more, but this depends on the quality of your car, how well you maintain it and your driving style.

For example, if you do a lot of stop-start city driving, your clutch is likely to wear out sooner as you'll be shifting between lower gears more frequently.

If you're experiencing any of the below symptoms, you may need a clutch replacement:

  • Spongy, sticking, vibrating or loose clutch pedal when pressed


  • Squeaking or grumbling noise when pressed


  • Ability to rev the engine, but poor acceleration


  • Difficulty shifting gear


  • 'Slipping' clutch, causing a momentary loss of acceleration.

Be sure to get in touch if you feel you have an issue with your clutch, it is always better to have a look sooner rather than later!
