What is the Difference between Automatic and Manual Transmissions?
Automatic and manual transmissions are both used to change a vehicle’s gear ratio so that it can perform more effectively and efficiently. These systems work in very similar ways, with the primary difference between these two transmissions being the way in which the driver interacts with them. In addition to these two basic styles, it is also possible to find a semi-automatic transmission, which blends elements of both. Cars need to change gear ratios to work properly. If a car is driven with a low gear ratio, it can only effectively function at low speeds, and acceleration would cause the engine to “redline,” or reach the point beyond which it cannot operate very well. High gear ratios are needed for high speeds, but a car can’t be driven at a high gear ratio when it is going slowly. Hence, transmissions are needed to allow the gear ratio to be changed as needed.
