Symptoms of a Bad Gearbox / Transmission

Recognising issues early can save money and prevent further damage. Look out for these tell-tale signs:

• Whining or Clunking Noises – humming, buzzing, or clunking often indicates failing bearings or internal wear.
• Lack of Response – delayed gear changes or hesitation means the transmission isn’t engaging correctly.
• Burning Smell – often caused by overheating transmission fluid or internal friction.
• Leaking Fluid – transmission fluid under the car is one of the clearest warning signs.
• Grinding Gears – in manuals, this can point to a worn clutch or synchronizer issues; in automatics, it may feel like rough, noticeable shifts.

Signs of a Bad Clutch

The clutch is critical for changing gears — and like all mechanical parts, it wears out over time. Depending on your driving style, a clutch can last anywhere from 50,000 to 100,000 miles or more. Stop-start city driving, frequent gear changes, and aggressive driving can shorten its life.

Common symptoms of clutch failure include:

• Spongy, sticking, vibrating, or loose clutch pedal
• Squeaking or grumbling noises when pressing the clutch
• Engine revs but poor acceleration (slipping clutch)
• Difficulty engaging gears smoothly
• Momentary loss of acceleration during shifts

If you notice these issues, it’s best to arrange an inspection or replacement before further damage occurs.
