What are the causes of abnormal noise when the Nissan Sylphy CVT transmission fails to engage gear?
1 Answers
There are many reasons for abnormal noise when the Nissan Sylphy CVT transmission fails to engage gear. Bearing abnormality: When bearings wear out, their clearance increases and fitting precision decreases; when bearings are damaged, they cannot operate normally, resulting in abnormal noise, and may even damage transmission components, causing noise. Abnormal lubrication condition: Insufficient lubricant or excessively high viscosity leads to poor lubrication. In this case, the corresponding lubricant (grease) should be replaced; otherwise, it will accelerate transmission wear and shorten its service life. Transmission abnormality: The bolts on the transmission housing (end cover) are loose. Vibration during use causes the bolts to loosen, so regular inspection is necessary.
