搭载同一发动机的车型在升级更多档位的变速箱后，加速都有所提升，但是“档位越多，提速越快”并不构成因果逻辑。汽车的加速性能由变速箱能承受的起步转速、变速箱的换挡速度、以及前几个挡位的齿比共同决定的，这些都跟车企的标定密切相关，跟挡位的数量没有太多关系。
The vehicle that carries the same engine increases the speed of the gearbox after the upgrade of more gear, but "the more the gear, the faster the speed" does not constitute a causal logic. The acceleration performance of a car is determined by the starting speed of the gearbox, the gear shift speed, and the tooth ratio of the previous gear, which are closely related to the calibration of the car enterprise, and have little to do with the number of the gears.
自动变速箱的诞生，原意是想将驾驶者的左脚解放出来，并降低驾驶车辆的难度，提高驾驶的舒适度。事实证明，自动变速箱确实更适用于拥挤的城市化生活，因此，成了全球车企争先研发的重点。

The birth of the automatic transmission is intended to liberate the driver's left foot, reduce the difficulty of driving and improve driving comfort. It turns out that the automatic transmission is more suitable for the crowded urbanization life, so it has become the focus of research and development of the global car companies.
设计多挡位变速箱的初衷确实是为了达到更好的燃油经济性，大多数6挡自动变速箱肯定比3挡的油耗要低。多挡位能带来更宽的齿比范围，较高挡位齿比也能更小，从而使发动机高速巡航的转速更低，油耗也就越低，但实际情况并不。
The purpose of designing multi shift gearbox is to achieve better fuel economy. Most of the 6 transmission automatic gearboxes must be lower than the 3 gear fuel consumption. Multi gear can bring a wider range of tooth ratio, and the highest gear ratio can be smaller, so that the speed of the high speed cruising of the engine is lower and the fuel consumption is lower, but the actual situation is not absolute.
换挡的平顺受很多因素影响，但挡位的多少起不了决定性作用。挡位多只能说明齿比落差比较小，发动机转速差比较小，但不直接说明换挡平顺。自动变速箱也一样，液力变矩器取代离合器的存在决定了“旋律”的跌宕起伏，而车企对液力变矩器的标定，比如液体粘度、升降挡时机、转速补偿等都直接影响到变速箱的顺滑程度。
Shifting is affected by many factors, but the number of gears is not decisive. More gear can only show that the gear ratio is small, and the engine speed difference is relatively small, but it does not directly explain the shifting smoothly. Automatic transmission is the same, the existence of the torque converter to replace the clutch determines the "Melody" of the ups and downs, and the car enterprise calibration of the torque converter, such as liquid viscosity, lifting gear timing, speed compensation and so on directly affect the speed of the speed of the gearbox.
