Introduction
The word ‘Transmission’ means the whole of the mechanism that transmits the power from the engine crankshaft to the rear wheels, providing the suitable variations of the engine torque at the road wheels, whenever required.

Gear Ratio• It is the ratio of the no. of teeth on the driver wheel to
no. of teeth on the driven wheel or the speed of rotation of the driver to the driven .
For example: Gear ratio, G=(10/20) = 1:2 (smaller gear is the driven)
20 Teeth
10 Teeth
