What causes oil leakage in the automatic transmission of the Lavida?
3 Answers
Oil leakage in the automatic transmission of the Lavida is likely caused by corrosion and aging of the sealing ring, or it could be due to an issue with the oil seal. Specific reasons: More than 90% of oil leakage problems occur because the rubber sealing rings inside the transmission are exposed to alternating hot and cold temperatures over time, causing the sealing rings to lose a significant amount of plasticizers and softeners, leading to corrosion, aging, and hardening. Initially, it may start as seepage, gradually progressing to dripping, and over time, the sealing ring may break. Solution for this issue: The sealing ring needs to be replaced. If replacing the sealing ring does not improve the situation, then check if the issue lies with the oil seal.
I've encountered the issue of oil leakage from the automatic transmission of the Lavida many times, and there are usually several common causes. The most frequent one is the aging or damage of the oil seal. The sealing rings around the transmission can harden and crack over time, causing oil to slowly seep out. Another common cause is loose oil pan screws or a damaged oil pan itself, which can easily occur if it hits a rock or something similar. Oil can also leak from loose connections in the pipelines. Additionally, if there are cracks in the transmission casing, oil will leak out, possibly due to impact or wear. Once you notice oil stains under the car, don't ignore it—take it to a repair shop immediately. Ignoring oil leaks can lead to overheating and wear of the transmission, and replacing the entire unit later will be costly. During regular maintenance, inspecting the chassis can help detect minor issues early and prevent major problems. Driving safety is the top priority, so never delay addressing such issues.
I once encountered a transmission oil leak issue with my own Lavida. That day, I was startled to find a puddle of oil under the car in the garage. When I took it to the repair shop, the mechanic said the sealing ring was damaged, which tends to age under high temperatures and vibrations, causing oil to seep out. He also checked the oil pan screws and found them slightly loose. Fortunately, the problem was caught early, preventing more significant damage. I recommend other car owners to regularly inspect the vehicle's undercarriage for any abnormal oil stains and avoid frequent driving on rough roads to reduce wear. A significant oil leak can lead to insufficient lubrication in the transmission, causing jerky movements or overheating, which is extremely dangerous. Dealing with such issues can be costly and not worth the risk. Getting it fixed promptly ensures peace of mind on the road.
