Is Your Clutch Slipping? Signs, Causes and What to Do Next

You press the accelerator, the revs climb, and the car seems to hang back for a moment before catching up. That is the textbook feeling of a clutch slipping, and it nearly always gets worse rather than better.

Below we cover how to recognise it, why it happens, a simple safe check and what to do if it appears on a hill or with a loaded vehicle.

What does a slipping clutch feel like?

Slip is easiest to notice when the engine is working hard, such as accelerating in a higher gear, climbing a gradient or overtaking. The engine note rises but the car does not accelerate in proportion.

• Revs flare up while speed barely changes
• A smell like burning toast or hot paper
• Weak pull on hills or when loaded
• The bite point creeping higher up the pedal travel
• Slip that appears only in higher gears at first

Why does a clutch start to slip?

The friction material on the clutch plate wears away with use, just like brake pads. As it thins, the pressure plate loses clamping force and the plate can skid against the flywheel. Normal wear is the most common cause.

Other causes speed things up. Oil from a leaking engine or gearbox seal can contaminate the plate. A weak pressure plate, an overheated or warped flywheel, or a hydraulic or cable adjustment fault that stops the clutch fully engaging can also cause slip. Riding the pedal, holding on the bite point on hills and towing heavy loads all create heat that shortens life.

How can you check for clutch slip safely?

Choose a quiet, flat, safe place and only try this if the car is otherwise driving normally. With the handbrake on and the engine warm, some drivers apply light acceleration in a high gear to see if the revs rise without the car moving properly. This puts extra strain on a tired clutch, so it is not a test to repeat.

A better option is simply to note when it happens and tell us. Slip under load, a high bite point and a burning smell together are a strong clue.

Is it safe to keep driving with a slipping clutch?

A mild slip may let you get home, but every slip generates heat that glazes the plate and can damage the flywheel, turning a clutch-only job into a larger one. Eventually the clutch may fail to drive at all, leaving you stranded.

If the car will not pull away, will not select gears or the pedal stays on the floor, do not keep driving. Get to a safe place and arrange help. Recovery is not something we provide, so you would need a recovery provider for the vehicle itself, and then message us about the repair.

How is a slipping clutch repaired?

The usual repair is a new clutch kit, normally including the friction plate, pressure plate and release bearing, with the flywheel inspected and replaced if damaged. If oil contamination was the cause, the leak should be found and fixed or the new clutch will slip again.

The price depends on the vehicle, how much needs to come out to reach the clutch and whether the flywheel or hydraulics need work, so it is quoted after we know the make, model and symptoms. We can also carry out the job on a mobile basis where the circumstances suit.
