What Causes Abnormal Noise When Pressing the Accelerator at Low Speed?
1 Answers
Abnormal noise when pressing the accelerator at low speed in a car may be caused by the following reasons: 1. The noise may be coming from the transmission. 2. For manual transmission models, the noise could be due to incomplete clutch disengagement. 3. There may be debris between the gears. As the gears collide with each other, the debris moves continuously, generating noise. 4. Parts inside the transmission may be damaged. Since transmission oil operates in high-temperature and high-pressure environments, it can produce a lot of sludge and impurities, causing the oil to thicken and reduce fluidity. This results in insufficient lubrication between components, leading to direct friction and increased mechanical wear, which causes the noise. Transmission oil should generally be replaced every 2 years or 40,000 kilometers.
