What are the causes of oil leakage at the transmission connection of the Lavida P?
2 Answers
The causes of oil leakage at the transmission connection of the Lavida P are as follows: Aging of transmission connection seals: This generally occurs in older vehicles. Typically, it happens when the airtightness of the seals deteriorates. Since oil seals are made of rubber, they can wear out naturally as the vehicle's mileage increases, or the springs that hold the seals in place may come loose. In such cases, it is necessary to disassemble the powertrain for repairs. Damage to the transmission cylinder block: When the engine is running, excessive internal pressure can cause the machine's internal components to bear too much stress. This excessive pressure can force the engine's gaskets to fail, allowing oil to leak through the damaged gaskets.
I've been in auto repair for over a decade and have encountered numerous cases of oil seepage at the transmission connection point on Lavida P models. The primary cause is usually aging sealant – after several years of driving, the seals become brittle and crack, allowing oil to leak out. Loose bolts are also very common, where excessive vibration causes oil to seep through gaps. Assembly issues can't be ruled out either, as some vehicles leave the factory with improperly tightened components. Worn oil seals tend to fail at higher mileages, with frequent high-speed driving accelerating leakage due to increased stress. Some owners have complained about potential design flaws in this model, citing inadequate durability of sealing materials at connection points. I recommend addressing any oil stains under the chassis promptly – first inspect the seals and bolts, as prolonged leakage can lead to transmission overheating and gear engagement issues, resulting in much costlier repairs later.
