What are the causes of the noise in the Lavida transmission?
2 Answers
Lavida transmission noise can be attributed to the following specific reasons: 1. Bearing wear and damage. When bearings wear out, the gap increases, leading to a decline in fitting precision. 2. Loose bolts on the transmission housing. During driving, vehicle vibrations can cause bolts to loosen, so regular inspections are necessary. 3. Long-term failure to replace the automatic transmission fluid. The fluid thickens over time, and its reduced flowability results in direct friction between components due to the lack of a protective layer. 4. Poor quality of automatic transmission fluid. Inferior transmission fluid has poor temperature resistance and is prone to oxidation, leading to sludge and residue buildup that can cause blockages.
There are many reasons for the noise in the Lavida's transmission, which may involve several common mechanical issues. I have encountered similar situations, and the most common cause is worn clutch plates. You may hear a clicking sound when shifting gears, especially in congested urban traffic where frequent clutch engagement is more likely to occur. Additionally, aging bearings can also cause a humming noise, sounding like the wheels are turning but not smoothly. When the transmission oil is insufficient or deteriorated, the lubrication effect is poor, increasing gear friction and resulting in a creaking sound. Regular maintenance should include periodic oil checks, with a full oil change every 40,000 kilometers or so to avoid clogging and more severe failures. If the noise occurs during acceleration or deceleration, it might be due to a faulty gear synchronizer, which requires professional diagnosis for repair. In short, early inspection is key to preventing minor issues from escalating into major repairs.
