Shifting Mechanisms

Mechanical devices that enable the driver to engage gears in such a way as to obtain the desired transmission ratio are called shifting mechanisms. They are called internal mechanisms if they are contained in the gearbox casing; they are called external when they are mounted partly on the outside of the gearbox casing, partly on the vehicle body; they connect the gearshift lever with the internal shifting mechanisms.

Shifting mechanisms perform an import function, because they are responsible for the response, the driver receives from the shift stick, and therefore for the easy use of the gearbox itself. An ideal response should be positive and precise.
