There are about more than a thousand small parts used in a single vehicle, but there are some parts that are more important than the other parts; and play a significant role in the working of the vehicle. One of those parts is the transmission of the vehicle, this is easily one of the most important components of the vehicle; as without it, the power generated by the engine would not be delivered to the wheels, and the vehicle would not move. There are two main types of transmissions found in vehicles, one is automatic, and the other one is manual. The manual is an old school tool that has been used since the beginning. On the other hand the automatic transmission is more newer in comparison, and offers an easier system. The other type of transmission that are common are, the dual clutch, that functions on similar principles to the manual transmission system, but they come with a computer control, which bridges the gap that is between the automatic and the manual transmission. The CTV (continuously variable transmission) has its way with individual gears, as it ramps up their power transmission; in comparison to the rules set. Many electric vehicles do not come with a transmission, and in them is a single fixed ratio; that is used to transmit the power to the wheels.
