Why Does a Manual Transmission Car Shudder When Starting?
1 Answers
Manual transmission starting shudder is generally caused by the wear and slippage of the clutch pressure plate and disc, mostly due to aging or quality issues. This requires replacing both the pressure plate and the disc simultaneously. If the driver is a beginner, the idle speed of driving school cars is usually higher, allowing smooth movement without pressing the accelerator. However, almost all manual transmission cars on the market require gently pressing the accelerator when starting. The details are as follows: 1. Fault Handling: Car starting shudder is a very common phenomenon, and there are many reasons that can cause it, either due to faults in the car itself or the driver's poor driving habits. Only after identifying the cause of the starting shudder can timely fault handling be performed. 2. Causes of Shudder: When a car starting shudder occurs, it is essential to carefully investigate the cause, as different shudder phenomena have different reasons. In case of starting shudder, it is recommended to let the engine idle, engage a low gear, slowly release the clutch pedal, and increase the throttle to start. If the body shakes significantly, it indicates clutch shudder. It could also be caused by broken or loose rivets on the driven plate, fractures in the driven plate steel sheet, or unbalanced rotating components. Additionally, loose engine mounts or misalignment between the transmission's first shaft and the engine crankshaft can also lead to car starting shudder.
