Is the Passat 1.8 transmission dry or wet?

[MacSamuel]

The Passat 1.8 transmission is a wet dual-clutch. Advantages and disadvantages of wet dual-clutch: The wet dual-clutch is stable and mature, not only achieving fast and smooth gear shifts seamlessly, but also preventing overheating at low speeds due to the cooling effect of the oil. The downside is that the wet dual-clutch has a complex structure, relatively larger size and weight, and significantly higher manufacturing costs compared to dry dual-clutch. Additionally, repairs are more time-consuming and labor-intensive, and the coolant needs to be replaced periodically. Working characteristics of wet dual-clutch: It is a type of clutch that uses oil to cool the friction surfaces. The heat generated during the engagement process due to sliding friction is continuously carried away by the cooling oil, effectively controlling the temperature of the friction surfaces and significantly reducing wear. Therefore, the wet clutch maintains stable performance over long-term use, with minimal changes in clamping force and friction coefficient.
