Why does the car still shake when slowly releasing the clutch?

[StMaya]

Possible reasons for shaking when slowly releasing the clutch are as follows: 1. Driven disc lining: Oil contamination or breakage of the driven disc lining, or uneven thickness of the driven disc causing shaking. 2. Clutch: Excessive spring tension of the clutch pressure plate causing clutch shudder. Stiffness of components such as the release sleeve and release fork shaft leading to clutch shudder. 3. Driving and driven discs: Bending of the driving or driven discs, or uneven height of the release levers causing clutch vibration. Additional information: 1. Clutch introduction: The clutch is installed between the engine and the transmission, serving as the assembly component in the vehicle's drivetrain that directly connects to the engine. Typically, the clutch is mounted together with the engine crankshaft's flywheel assembly, acting as the component that cuts off and transmits power between the engine and the vehicle's drivetrain. 2. Clutch function: Throughout the process from starting the car to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the drivetrain, cutting off or transmitting the power output from the engine to the drivetrain. Its role is to allow gradual engagement between the engine and the transmission, ensuring smooth vehicle starting; temporarily disconnecting the engine from the transmission to facilitate gear shifting and reduce shifting impact; and providing separation during emergency braking to prevent overload of the transmission and other drivetrain components, thus offering certain protective functions.
