What causes the transmission noise in Wuling Hongguang S that disappears when the clutch is pressed?
2 Answers
Wuling Hongguang S produces abnormal noise after starting, which disappears when the clutch is pressed. This is transmission noise. When the clutch is pressed, the power connection between the engine and the transmission is cut off, and the transmission stops rotating, naturally eliminating the noise. Check the transmission gear oil, as insufficient or deteriorated gear oil can cause transmission noise. Below is additional information: Solution: Engine noise indicates that the technical state of a certain engine mechanism has changed. This is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some noises may even predict potential catastrophic engine damage. Therefore, when engine noise occurs, it should be repaired promptly to prevent the fault from worsening.
I've had similar experience with the Wuling Hongguang S before, where the transmission made abnormal noises that disappeared when the clutch was pressed. The main reason is wear and tear on the gears or bearings. When the clutch is pressed, the power transmission of the gearbox is disconnected, reducing friction, hence the noise disappears. The most common issues are a faulty input shaft bearing or problems with the synchronizer, causing gear friction during shifting. This could be due to long-term rough driving or not changing the transmission oil on time. It's recommended to immediately check the transmission oil level and quality. If the oil is dirty or insufficient, try replacing it with new oil. Delaying repairs could lead to complete bearing failure, making repairs more expensive. The Wuling Hongguang S is an older model, so remember to have it thoroughly inspected by professionals periodically. Don't wait until the problem becomes severe—safe driving is the top priority.
