Oct 13, 2023· The transmission system in automobile is a vital component of any vehicle, serving as the bridge between the engine''s power and the wheels that drive the vehicle forward. This system enables seamless control over the speed and direction of the automobile, allowing it to navigate various road conditions and terrains.
However, the vehicle speed would be limited by the engine''s top speed. The transmission allows the vehicle to operate over a larger speed range, while keeping the engine speed within operating range. In most automobiles, engine power depends solely on the accelerator position. Different conditions demand different power requirements.
