A high-quality automobile gearbox oil pan pad needs to have the following characteristics:

1. High-temperature resistance: The oil pan gasket of the wave box needs to be stable in high-temperature environment, not easy to deform or melt, and ensure the sealing performance and the normal work of the internal parts of the wave box.

2. Oil resistance: High-quality oil pan gasket of wave box needs to have good oil resistance, can resist the corrosion of lubricating oil and chemicals, and maintain sealing performance and long-term stability.

3. Elasticity and compressibility: The oil pan gasket of the wave box needs to have certain elasticity and compressibility, which can effectively fill the gap between the bottom shell of the wave box and the transmission system, and ensure the sealing performance and leak-proof effect.

4. Wear resistance: The oil pan pad of the gearbox needs to have good wear resistance, which can resist the friction and wear of the transmission system and prolong the service life.

5. Sealing performance: The oil pan gasket of the wave box needs to have good sealing performance, which can effectively prevent the leakage of lubricating oil and maintain the lubrication and protection effect inside the wave box.

Generally speaking, a high-quality automobile gearbox oil pan gasket should have high temperature resistance, oil resistance, elasticity, wear resistance and good sealing performance to ensure the normal operation and long-term stability of the gearbox system.
