Manual vs. Automatic- the never-ending debate that we can’t really see coming to an end any time soon. While we have different reasons to like both transmissions, today we’re paying tribute to the manual gearbox that’s been serving us well for many years and continues to be the most popular and commonly used type of transmission.

The video below shows in a simplified manner how the manual transmission works by employing both illustrations and animations. It sheds a light on questions such as why the transmission takes a central role in the functioning of the vehicle, how the transmission transfers the power produced by the engine to the wheels, etc. This demonstration further serves as a theoretical introduction to the workings of the manual transmission with reverse gear.

Why does the transmission matter? The transmission is a mediator, the bridge if you wish, through which the power produced by engine flows to the drive wheels. Its main function is to regulate the speed and torque available to the drive wheels depending on the driving condition.

Let’s, for example, imagine that you’re about to drive up a hill – to do so you need more torque, which requires you to lessen the speed at the transmission, and thus attain higher torque for the same power input. However, if we are driving on a motorway and count on more speed rather than torque, then what you need to do is increase the transmission speed. So ultimately for the manual transmission to work, it answers to the simple principle of ‘gear ratio’.
