超速行驶是什么?超速行驶是最高的齿轮自动传输。

2·Some cars have an extra gear called overdrive which allows them to travel long distances using less gasoline.

3·When it comes to automatic transmission, there is always overdrive - which is the highest gear - in place.

当谈到自动变速器，总是有超载——这就是最高的齿轮-在的地方。

4·It has an aggressive 4.07:1 first gear ratio that delivers strong launches, but also provides tall overdrive ratios that decrease engine RPM and provide better fuel efficiency.

它有一个积极的4.07：1第一齿轮比，提供强大的发射，而且还提供高过载率的降低发动机转速，并提供更好的燃油效率。

5·This is because the transmission may be shifting back and forth between the overdrive and the second highest gear.

这是由于传输可能转移间来回地超载，第二个最高的齿轮。
