Transmissions sometimes fall behind engines in the public's perception of car engineering. Nonetheless, the reality is unmistakable: the gearbox is just as important to performance, efficiency, and driving enjoyment as the engine it serves. Modern gearboxes have advanced much beyond the classic gear stack. Today's most modern systems combine intricate mechanical design, clever electrical controls, and software that anticipates how you want the automobile to act. They make automobiles faster, smoother, more efficient, and more fun to drive. Here are the top 9 most advanced transmissions ever built in production vehicles.
