Clutch Judder
Clutch judder is a shaking or vibration felt when pulling away as the clutch engages.
What is Clutch Judder?
It is most noticeable in first gear and reverse. Oil contamination, worn friction material or worn mounts can cause it. Dual-clutch transmissions can also show judder. Oil from a leaking crankshaft seal or gearbox input seal can contaminate the clutch disc. A worn dual-mass flywheel can cause similar vibrations.
How it works
Uneven grip of the clutch disc makes the drivetrain grab and slip repeatedly.
Why it matters for your car
Check engine and gearbox mounts before replacing the clutch. Some dual-clutch judder can be improved with a software update or adaptation.
