What is Slipping the Clutch?

March 14, 2024 | Victor Lukasso

Slipping the clutch is a term common among manual car drivers. This is a major problem and must be resolved immediately if you want to engage and disengage between gears effortlessly.

In simple terms, slipping the clutch is a phenomenon where the clutch fails to appropriately engage or disengage the gearbox (transmission), causing the engine to slip out of gear or struggle to remain in a particular gear during acceleration.

This doesn’t just affect your ability to switch between gears; it can also make driving frustrating and even result in accidents on the highway.

This article will discuss the meaning, causes, symptoms, and repairs of slipping the clutch or clutch slippage in a manual transmission.


What Does Slipping Your Clutch Mean?

Slipping the clutch refers to a situation in which the clutch disc, a crucial component in manual transmissions, fails to engage properly with the flywheel and pressure plate, causing the vehicle to slip out of gear or struggle to remain in gear during motion.

The clutch connects and disconnects the engine’s power to the transmission, allowing the driver to change gears and control the vehicle’s speed.

When the clutch slips, the power transfer between the engine and the transmission does not occur as efficiently. This results in a loss of power and, consequently, a decrease in the vehicle’s performance.

This also means that your wheels won’t move at the correct speed they should when connected to the right gears because the gear is always going out or is having issues maintaining a static gear during acceleration.

Causes of Slipping the Clutch

If your clutch starts slipping, it’s a sign that it has started failing, and it’s time for a change. However, this can happen for several reasons:

  1. Worn-out Clutch Disk or Plate
  2. Aggressive Driving/Gear Switching Technique
  3. Oil contamination/leakage
  4. Incorrect clutch adjustment
  5. Faulty clutch components
  6. Hot Areas

Worn-out Clutch Disk or Plate:

One of the primary reasons for clutch slippage is a worn-out clutch disc. Over time, the friction material on the disc wears thin, reducing its ability to grip the flywheel and pressure plate effectively. Regular wear and tear from everyday driving contribute to this issue.

Aggressive Driving/Gear Switching Technique:

Aggressive driving, such as frequent rapid acceleration and abrupt gear changes, can accelerate clutch wear and contribute to slipping.

Avoid habits such as changing between gears too rapidly or not properly engaging the clutch before attempting to change gears. Adopting these smooth driving habits will extend the life of your clutch system.

Oil Leakage

If oil leaks into the clutch assembly, it can saturate the friction material on the clutch disc, reducing its grip.

Incorrect clutch adjustment

If the clutch is not adjusted correctly, it may not engage and disengage as intended, leading to slipping. Mechanics often recommend periodic clutch adjustments to ensure smooth operation.

Heated or hot Area

You may encounter this occasionally if you live in a region with excess heat.

Faulty Clutch Components

Components such as the pressure plate and flywheel play a vital role in the clutch system. If any of these components are damaged or malfunctioning, they can contribute to slipping issues.

What a slipping Clutch Feels Like?

Here are some symptoms that’ll help you identify clutch slippage in your vehicle:

  • Difficulty changing gears: If switching through gears becomes difficult, it indicates an underlying problem in the clutch.
  • Loud noise when applying the clutch: if you hear a squeak or noise when the clutch pedal is compressed, it’s time to check your clutch.
  • Poor Acceleration: clutch slippage usually leads to poor acceleration, making the car move slower because of inadequate power getting to the wheels.
  • Sticky or Spongy Clutch: if the clutch feels Spongy or sticks at a particular point when removing your legs, it’s time to see the mechanic.
  • A burning smell: a burning smell can signify many things of which a slipping clutch isn’t exempted.
  • High Revs:
  • Loss of Momentum: if you notice that your car suddenly loses acceleration while driving, then it could be a result of clutch slippage. This happens because the car is unable to maintain a particular gear.

How Do You Fix a Slipping Clutch?

Fixing a slipping clutch isn’t a DIY task; you should consider taking your vehicle to a mechanic for inspection and proper fixing.

Also, it’s not advised to continue driving with a slipping clutch as it may result in accidents or leave you stranded on the road. Ensure to have your clutch checked by a mechanic every 60,000 miles.

However, here are a few components you can replace or fix if you notice clutch slippage.

Clutch Plate Replacement

Replacement is often the most effective solution if the clutch disc is significantly worn. A skilled mechanic can assess the extent of wear and replace the clutch components as needed.

Fixing Oil leaks

Regular inspections of the engine and transmission for signs of leaks can help address this issue before it leads to clutch slippage.

Clutch Adjustment

Adjustments may be necessary to ensure proper function if the clutch engages or disengages too quickly or slowly. This is a relatively straightforward task that a mechanic can perform during routine maintenance.

Replace damaged components

If components such as the flywheel and/or the pressure plate are faulty, you must have them replaced instantly. Don’t ignore subtle signs from these components because they can exacerbate clutch slippage and cause more transmission problems.

Change your driving skills.

Drivers can play a role in preventing clutch slippage by practicing smooth driving habits. Avoiding aggressive acceleration, abrupt gear changes, and excessive clutch slipping.

Visit a Mechanic

If you don’t know how to troubleshoot the problem, call the attention of a mechanic. This is preferred since they may also notice other problems with the transmission.

N.B: in another context, “slipping the clutch” is also referred to as “feathering the clutch,” which is a clutch control technique used to describe a skill used by drivers of manual cars to achieve a smoother and more controlled power delivery.

Feathering the clutch involves delicately manipulating the clutch pedal to control the engagement of the clutch disc with the flywheel and pressure plate.

Unlike fully engaging or disengaging the clutch, feathering allows for a partial engagement, providing a gradual and controlled transfer of power from the engine to the transmission.

However, this skill also increases wear on the clutch components over time, causing clutch slippage, which is being discussed initially.
