What Causes Vibration When Idling in D Gear?

[MacGarrett]

Causes of vibration when idling in D gear while stationary are as follows: 1. Vibration during first-gear start: This is likely due to the driver's habits. If the driver is a beginner, it's best to learn from experienced drivers and get familiar with the car's clutch. 2. Habit: If driving habits are ruled out, vibration during first-gear start may be caused by excessive wear of the clutch pressure plate. Manual transmissions primarily transmit power through the clutch, and the clutch pressure plate is responsible for transferring kinetic energy. The clutch pressure plate has a limited lifespan. Prolonged semi-engagement or the engine operating under excessive load can accelerate wear. 3. Wear: When the pressure plate wears to a certain extent, power transmission becomes less smooth, causing the car to vibrate and the engine speed to become unstable. The solution is to visit a repair shop or 4S store to have the clutch pressure plate replaced by technicians, which will resolve the issue.
