What are the causes of abnormal noise in the Vios transmission?
1 Answers
Abnormal noise in the Vios transmission may be caused by poor fuel quality when the engine burns oil; wear of the front and rear bearings of the transmission; wear of the gear shift fork groove or wear of the lower working surface of the gear lever; excessive wear of the gear teeth. Poor fuel quality when the engine burns oil: During driving, friction sounds may occur due to insufficient or deteriorated lubricating oil. It is necessary to add oil or check the oil quality, and replace it if necessary. Wear of the front and rear bearings of the transmission: Abnormal noise in the transmission when in neutral, which disappears when the clutch pedal is pressed, is usually caused by wear or looseness of the front and rear bearings of the transmission. If the noise occurs in any gear, it is mostly due to the rear bearing of the second shaft. Severely loose or damaged bearings should be repaired or replaced. Wear of the gear shift fork groove or wear of the lower working surface of the gear lever: If a dull and irregular noise occurs in a certain gear during driving, and the noise disappears when the gear lever is held by hand, it may be caused by wear of the gear shift fork groove or wear of the lower working surface of the gear lever. Disassembly, inspection, repair, or replacement is required. Excessive wear of the gear teeth: If a noticeable noise occurs after shifting into a certain gear during driving, it is likely due to excessive wear of the gear teeth. If a periodic noise is heard, it may indicate damage to individual teeth. Sudden impact sounds during gear shifting may suggest broken teeth. The transmission should be promptly disassembled for inspection, and repairs or replacements should be carried out.
