What is the S gear in automatic transmission?
1 Answers
Automatic transmission S gear is the sport mode of a car, which can be used during aggressive driving or overtaking. Almost every automatic transmission car has an S gear, and even if there is no S gear, there is a sport mode switch. There are three common types of automatic transmissions in cars: AT transmission, CVT transmission, and DCT transmission. DCT transmission is a relatively popular automatic transmission. This transmission is essentially a dual-clutch transmission, developed based on manual transmission. Its structure is similar to that of a manual transmission, except that the manual transmission has an additional set of clutch and shift control mechanism. One set of clutches in the dual-clutch transmission controls the odd-numbered gears, while the other set controls the even-numbered gears.
