What does 7dct transmission mean?

7dct transmission refers to a 7-speed dual-clutch transmission. DCT Transmission: The main body of a DCT transmission is a manual transmission, which can also be considered an upgraded version of a manual transmission. The DCT transmission has two sets of clutches, primarily responsible for shifting odd-numbered gears and even-numbered gears (including neutral gear), respectively. During operation, these two sets of clutch plates work alternately to complete the upshifting and downshifting tasks of the DCT transmission. Generating significant heat: During the shifting process, the friction plates of the two clutches generate a substantial amount of heat due to intense friction. This is particularly evident when driving in congested urban areas, where frequent stop-and-go conditions occur. The transmission shifts gears more frequently, requiring the vehicle's transmission clutches to work continuously, thus causing the DCT transmission to generate significant heat.
I've always found it quite interesting to understand transmission codes. Recently, many people have been asking about 7DCT, which actually refers to a 7-speed dual-clutch transmission. DCT is the abbreviation for Double Clutch Transmission. This type of transmission contains two sets of clutches, controlling odd and even gears respectively. When you're using 3rd gear, the other clutch has already quietly prepared 4th gear, making gear shifts so fast that you can barely feel any power interruption. It's much more responsive than a regular automatic transmission and is particularly fuel-efficient, which is why many sports cars and family vehicles prefer using it. However, it's worth mentioning that during low-speed crawling in traffic jams, you might occasionally feel a slight jerk underfoot, which is characteristic of this type of transmission.
