What causes shaking when idling in first gear?

[VonHope]

Here are the specific reasons for shaking when idling in first gear: 1. Driving habits: Shaking during first gear starts is likely caused by the driver's habits. 2. Excessive wear of the clutch pressure plate: Manual transmissions primarily transmit power through the clutch, and the clutch pressure plate is mainly responsible for transferring kinetic energy. The clutch pressure plate has a lifespan, and prolonged semi-engagement or the engine operating under excessive load can accelerate wear. When the pressure plate wears to a certain extent, power engagement becomes less smooth, causing the car to shake and the engine speed to become unstable. 3. Wear of the flywheel and clutch disc: Irregular wear of the flywheel and clutch disc, key components of the clutch, can lead to misalignment. During engagement, the clutch disc cannot smoothly engage.
