HOW IT WORKS: Car Transmission (720p)
This educational HD video describes how a car transmission works in modern vehicles. In mechanical engineering, a transmission is a mechanical device that uses gears to improve mechanical efficiency, employing the ancient concept 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.

Transmission whining/grinding noise on a 97 740iL
UPDATE: Resolved the issue in June 2012 by performing a transmission fluid change, replacing the Febi filter the shop installed with a Genuine BMW Filtran filter. No noises at all in the last two months. Whining noise my 740iL makes when accelerating with a cold engine.
