What Causes the Transmission Noise in Leiling?
4 Answers
The abnormal noise in the Leiling's transmission is mainly caused by bearing wear and looseness, as well as improper meshing between gears. Common reasons for automatic transmission noise include: failure to repair the transmission in time after water ingress, which can lead to a series of transmission issues such as oil leaks, noise, and impact faults. Long-term failure to replace the automatic transmission fluid can cause the fluid to thicken and lose its effectiveness over time, resulting in direct friction between components without a protective layer, thereby accelerating mechanical wear. In severe cases, this can damage transmission components like the planetary gear set and differential, leading to abnormal noise. The use of inferior transmission fluid, which is of low quality or counterfeit, has poor temperature resistance and is prone to oxidation, forming sludge and residues that clog the transmission filter and lubrication channels. This increases friction within the transmission components, causing noise faults. Abnormal transmission noise is primarily due to bearing wear and looseness, as well as improper gear meshing, resulting in noise.
I've been driving my Levin for several years and have encountered transmission noise issues a few times. The most common causes are insufficient or deteriorated transmission fluid - without proper lubrication, the gears grind dry and produce abnormal sounds. Another possibility is bearing aging; after prolonged use, internal components wear out and create noises, sometimes resembling squeaking or creaking sounds. If the noise worsens during gear shifting, it might indicate clutch slippage or synchronizer problems, which are more common in manual transmissions. Don't ignore minor noises - delaying repairs could lead to complete transmission failure with costly consequences. Personally, I check fluid levels and change intervals whenever I hear unusual sounds. I recommend regular maintenance, especially for city driving with frequent starts and stops. Additionally, while Levin's transmission design is quite durable, problems can emerge over time or with heavy loads. Safety first - get it checked at a professional shop promptly.
I just bought a Corolla not long ago, and after driving it for a few months, I suddenly heard noises from the transmission, like a rustling or clicking sound, which really freaked me out. I asked a car-savvy friend, and he said it might be due to insufficient or dirty fluid, causing the oil pump to supply oil unevenly, leading to the noise. Another possibility is loose internal parts, like increased gear clearance, especially noticeable during slow gear shifts in traffic jams. As a beginner, I don’t know much about mechanics, but I understand this could affect the driving experience and even damage the transmission. Later, I learned to check the dipstick and top up the fluid if the level was low. My friend reminded me not to wait until the noise gets worse before addressing it—listen to the engine sounds regularly and get it fixed early if anything seems off. Also, avoid stomping on the accelerator in daily driving to protect the transmission components and extend their lifespan.
Frequently encountering cases of transmission noise in the Leiling, it's usually caused by mechanical wear. For example, a bad bearing sounds like friction noise, and gears lacking oil will squeak. If it's an automatic transmission, a fault in the electronic control module can also trigger noise, similar to a ticking sound. During inspection, use a diagnostic tool to scan for fault codes. A simpler approach is to check if the oil color has turned black or become thin, then replace it with new oil. Don't neglect regular oil changes, as poor oil quality accelerates part wear. If you encounter noise, avoid driving long distances to prevent bigger issues. The Leiling often has minor issues with small components, but overall it's reliable. Fixing problems early ensures no major troubles.
