What are the reasons for the abnormal noise in the Lavida transmission?
2 Answers
Reasons for abnormal noise in the Lavida transmission: 1. Automatic transmission water ingress: If water enters the automatic transmission and is not repaired in time, it can cause a series of transmission failures, such as oil leaks, abnormal noises, and jerking. 2. Not changing the transmission oil: Long-term failure to change the automatic transmission oil can cause the oil to thicken, losing its effectiveness over time. Without a protective layer between components, direct friction occurs, exacerbating mechanical wear. 3. Using inferior transmission oil: Low-quality or counterfeit transmission oil has poor temperature resistance, is prone to oxidation, and can form sludge and deposits, clogging the automatic transmission filter and oil passages. This increases friction between internal components, leading to abnormal noise faults.
I am quite concerned about the causes of abnormal noises in the Lavida's transmission. Common issues include bearing wear leading to sharp sounds, especially noticeable during gear shifts; poor gear meshing may cause clicking noises; insufficient or contaminated transmission fluid can result in inadequate lubrication, amplifying mechanical friction; faults in the electronic control module can sometimes cause abnormal transmission behavior; and loose or improperly installed drive shafts may also generate unusual noises. During diagnosis, it is recommended to first check the transmission fluid level and condition. If the fluid is black or has a burnt smell, it indicates internal damage. When dealing with the issue, I pay attention to the frequency of the noise—for example, noises during low-speed acceleration are often related to gear problems. If not addressed promptly, it may develop into a complete transmission failure, leading to high repair costs. It's advisable to schedule an inspection at a professional shop in advance. For daily driving, maintaining smooth operation can help extend the lifespan of the components.
