Is the transmission of the Mercedes-Benz GLA200 wet or dry?

[DeChristopher]

The Mercedes-Benz GLA is equipped with a wet 7-speed dual-clutch transmission. Advantages and disadvantages of wet dual-clutch transmissions: Wet dual-clutch transmissions are stable and mature, capable of achieving fast and smooth gear shifts without interruption. Additionally, since the transmission fluid helps dissipate heat at low speeds, overheating is avoided. The downside is that wet dual-clutch transmissions have a more complex structure, larger size, and greater weight, resulting in significantly higher manufacturing costs compared to dry dual-clutch transmissions. They also require more time and effort for maintenance, along with regular replacement of cooling fluid. Working characteristics of wet dual-clutch transmissions: This type of clutch uses transmission fluid to cool the friction surfaces. The heat generated during engagement due to slippage is continuously carried away by the cooling fluid, effectively controlling the temperature of the friction surfaces and significantly reducing wear. As a result, wet clutches maintain stable performance over long-term use, with minimal changes in clamping force and friction coefficient.
