HOW IT WORKS: Car Transmissions (720p)
This short educational video describes how a transmission works. In physics, a transmission is a mechanical device that uses gears to improve mechanical efficiency, employing the ancient technology of the lever. Its a machine that requires a power source and a power transmission system, which provides controlled application of the power, automatically or manually. Often the term "transmission" refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to some other kind of mechanism, such as a differential, which would apply that power to the wheels.
