Is a 7-speed wet dual-clutch transmission a manual transmission?
2 Answers
7-speed wet dual-clutch transmission is an automatic transmission, also known as a manual-automatic transmission. Both manual-automatic transmissions and dual-clutch transmissions are types of automatic transmissions, representing an upgraded product for automatic vehicles, providing drivers with a more comfortable driving experience. When these two types of transmissions are used in manual mode, shifting only requires moving the transmission lever. Below is an introduction to dual-clutch transmissions: Types: Dual-clutch transmissions come in dry and wet types. Wet dual-clutch: A wet dual-clutch refers to a multi-plate clutch system where one large and one small clutch are coaxially installed together, both housed in a sealed oil chamber filled with hydraulic fluid. Therefore, the wet clutch structure offers better adjustability and excellent thermal properties, capable of transmitting higher torque. Dry dual-clutch: The dry dual-clutch was developed based on the technology of the 6-speed DQ250 wet dual-clutch, simplifying the related hydraulic systems. Structure of dual-clutch transmissions: The structure of a dual-clutch transmission is very similar to that of a manual transmission. It has two sets of clutches, each responsible for shifting between even and odd gears, significantly improving shift speed.
I remember when I drove a manual transmission car, stepping on the clutch pedal and shifting gears manually was a daily routine—exhausting. Later, I switched to a car equipped with a 7-speed wet dual-clutch transmission, and the difference was huge—this thing isn’t a manual at all; it’s an advanced form of automatic transmission. With a manual, you have to operate the clutch pedal and gear lever yourself, but with a dual-clutch, the computer controls two clutches working alternately: one handles odd-numbered gears, the other even-numbered gears, shifting automatically—you just press the accelerator. I’ve driven it on the highway, and the gear changes are incredibly smooth, like silk gliding. The wet design also includes an oil cooling system to prevent overheating and wear, which is a lifesaver in traffic jams. Some people mistakenly think its manual mode makes it a manual transmission, but that’s just simulated play—it’s fundamentally automatic, clearly categorized. Modern cars favor this design because it offers quick acceleration and fuel efficiency, but daily maintenance requires frequent transmission oil changes to avoid jerky shifts. In short, once you’ve tried it, you’ll understand the convenience of an automatic car.
