Whether changing transmission oil can solve the buzzing noise depends on the specific situation. The exact cause of the abnormal noise should be diagnosed at a repair shop, as different causes require different solutions. Wear and damage of bearings: When bearings wear out, their clearance increases, and their fitting precision decreases. When bearings are damaged, they cannot operate normally, resulting in abnormal noise. This may even damage the transmission components, worsening the problem. In this case, simply changing the transmission oil will not solve the issue, and new bearings and related parts need to be replaced. Insufficient or dirty transmission oil: Insufficient or dirty lubricating oil will lead to poor lubrication, causing the transmission to produce abnormal noise and accelerating wear. In this scenario, changing the transmission oil can resolve the problem.

Should You Depress the Clutch When Turning a Car?

When turning a car, you should not depress the clutch. Pressing the clutch is equivalent to putting the vehicle in neutral, causing it to lose engine braking force, which can endanger driving safety. The functions of the clutch are: 1. Gradually increasing the driving force of the car to allow for a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload of the transmission system; 4. Reducing torsional vibration impact from the engine and extending the lifespan of transmission gears. Severe clutch wear can lead to: 1. Slipping of the car and insufficient power; 2. Difficulty in starting the car and ignition problems; 3. Poor climbing performance and increased fuel consumption. The working principle of the clutch is: 1. When the inner race is fixed, the outer race can rotate freely in the clockwise direction without locking the wedge block; 2. When the outer race rotates counterclockwise, the wedge block locks, preventing the outer race from rotating.
