What causes the transmission noise in Haval H6?
3 Answers
During low-speed driving, if the vehicle frequently emits irregular "clattering" noises, it is likely due to poor gear meshing inside the transmission. It is recommended to promptly remove and inspect the transmission. If the poor meshing is severe, replacing the meshing components is advised. If noticeable noise occurs during gear shifting, it may indicate severe wear on the lower working surface of the gear lever. In such cases, it is recommended to visit a professional auto repair shop for expert inspection and repair. Below are more related introductions: Methods to address transmission noise: 1. Add lubricating oil to the transmission housing and connections. If necessary, replace internal metal components. 2. Repair loose or damaged bearings inside the transmission. If the budget allows, replacing the bearings can resolve the noise issue.
I recently helped a friend deal with a transmission noise issue in their Haval H6, where there was a clicking sound during low-speed gear shifts. Upon inspection, we found that the transmission fluid had turned black after 50,000 kilometers of use, and the insufficient fluid level caused poor lubrication of the gears. After replacing the fluid, the noise disappeared. However, abnormal noises could also be due to worn bearings or gears, especially when there's a metallic grinding sound, which requires extra caution. I once experienced a situation where the bearings in my own car disintegrated, and the repair cost nearly 3,000 RMB. It's advisable to visit a 4S shop early for a computer diagnostic check, rather than letting minor issues escalate into major faults. Regular fluid changes are crucial—the Haval maintenance manual recommends changing the transmission fluid every 40,000 kilometers.
I've been driving for over 20 years, and there are several common causes for transmission noise in the Haval H6. Mechanically, it could be bearing wear, especially in high-mileage vehicles that produce a whining sound at 30-40 mph. Oil circuit issues are the most frequent, where deteriorated fluid can cause gear shift jerks along with noise. Electrical faults are rare, but a malfunctioning transmission sensor can also trigger abnormal sounds. Driving habits play a role too; prolonged half-clutch driving accelerates clutch plate wear. Last week, my neighbor's car had to replace the clutch three-piece set due to this. I recommend first checking the oil level and color yourself, then getting a professional inspection—don't trust roadside stalls lightly.
