What is the GM DSS Transmission?
1 Answers
DSS transmission is a dual-clutch transmission. Below is the relevant information: Dry Dual-Clutch: The dry dual-clutch transmission and wet dual-clutch transmission operate similarly, both having two sets of clutches—one for odd gears and one for even gears. The main difference lies in the connection medium between the driving and driven plates. The dry dual-clutch uses air for transmission, while the wet dual-clutch uses oil. Wet Dual-Clutch: The wet dual-clutch refers to a multi-plate clutch system where two clutches (one large and one small) are coaxially installed together. Both are housed in a sealed oil chamber filled with hydraulic fluid. As a result, the wet clutch structure offers better adjustment capabilities and superior thermal properties, allowing it to transmit higher torque.
