Manual transmission systems have the potential to improve fuel efficiency, enhance performance, and may reduce the average price of a vehicle Manual transmissions can tremendously improve the performance of cars, particularly those with smaller engines. They are considered by many drivers to be more fun to use, and may reduce gas consumption.
Manual transmissions can be found on most makes and models of cars, but are most common on sports cars, older vehicles, and cars with smaller engines. Manual transmission systems come in several different speeds, including four-speed, five-speed, and six-speed configurations. They vary in design complexity depending on their speed capacity; systems with the most gears have larger gear sets and components, and are slightly larger than their lower-speed counterparts.
Manual transmission systems, as a whole, have shorter gearing systems than automatic transmissions, which makes them rev more slowly, particularly when driving on the highway. Having a slower revolution rate ultimately makes manual systems more energy-efficient, which in turn allows them to reduce gasoline consumption.
Despite having several distinct advantages, manual transmissions have some drawbacks as well. They are found on a smaller variety of cars than automatic systems, and require more skill to operate. Frequent stopping and starting, such as during city driving, can easily wear out clutches and shifters, which in turn need more frequent replacement.
