What Is Clutch Judder?

Clutch judder is where the vehicle shudders with a vibrating sensation when engaging the clutch as it hits the biting point, or on the contrary, you may feel it when you disengage the clutch. It may feel as though the car is intensely shaking for a few seconds before being normal again and usually happens when setting off from a standstill.
