Why does the Lavida make abnormal noises when shifting into reverse gear?
2 Answers
Abnormal noises when the Lavida shifts into reverse gear may be due to issues with the engine or transmission. Here is a related introduction to the possible causes of abnormal noises when the Lavida shifts into reverse gear: 1. Engine abnormal noise: Symptom description: There are many possibilities for abnormal noises in the engine compartment, and most people judge the source of the noise based on the sound, which is usually a sharp metal sound or a whistling noise. Solution: Engine abnormal noise indicates that the technical state of a certain mechanism in the engine has changed. It is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can also indicate potential catastrophic damage to the engine. Therefore, when abnormal noises occur in the engine, timely repairs should be carried out to prevent the fault from worsening. 2. Transmission abnormal noise: Symptom description: If there is a "rustling" sound inside the transmission while driving, and it disappears when the clutch or accelerator is pressed, and there is a whistling-like sound when shifting gears. Solution: The transmission has many parts, and the causes of noise are also complex. When analyzing and judging, pay attention to: whether it is related to a specific speed, such as some planetary gears making noise that is more obvious around 50Km/h. Whether it is related to certain gears, which is very important for judging transmission faults. If a certain gear makes noise, it is definitely related to the components affecting the transmission of that gear; if all gears make noise, it is often a fault with the constant-mesh gear shaft or insufficient transmission oil. Whether it is related to specific actions, such as shifting up or down, starting, rapid acceleration, rapid deceleration, turning, etc., which are effective means to judge abnormal noises. Among them, changing speed and direction are particularly important for judging rear axle faults.
When I was driving my Lavida, I encountered a strange noise when shifting into reverse gear. It sounded like gears crunching, which was quite annoying. Later, I figured it might be because I was too hasty in my operation, shifting gears without fully depressing the clutch, causing the synchronizer to engage improperly. Or perhaps the transmission oil was low or too dirty, leading to insufficient lubrication and noise. Sometimes it's due to worn gear components, which is particularly common in Lavida manual transmission models. I'd recommend getting it checked at a 4S shop, changing the oil or adjusting the clutch. Don't delay, as minor issues can escalate into major transmission problems. Usually, shifting gears more slowly and developing good habits can save a lot of trouble.
