What are the causes of oil leakage at the transmission connection of the Lavida P?

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.

How to Determine the Position of Your Wheels?

Determining the position of your wheels can be done using the following methods: 1. Use the wiper blades to judge the wheel position. By observing the nodes on both sides of the wiper blades, you can determine the wheel's position, as the nodes indicate where the wheels will pass during driving. 2. Use the side mirrors to judge the wheel position. By observing the door handles on both sides through the mirrors, the point where the door handles align with the solid lines on the ground indicates the position the wheels have passed. 3. Use the center of the windshield to judge the wheel position. If the solid lines on the road align with the center of the windshield, it means that position is where the wheels are traveling.
