On the contrary, a car equipped with an automatic transmission will automatically select which is most appropriate for the given speed. Automatic transmissions are more user friendly and are the preferred transmission for consumers who are looking for their car to take them from point A to point B with the least amount of driver input.
Within a gearbox transmission, there are as few as two gears and the maximum number of gears is not strictly defined; however, most modern transmissions have between four and six gears. Each gear contained in any given gearbox will have a different ratio in sequence from low to high. A car will start out in first gear of speed increaser gearbox(the lowest gear) and as it accelerates, the transmission will climb through the gears until it reaches the proper gear for the sustained speed. To prevent the engine from stalling, the transmission will also need to descend through the gears as the car decelerates. Different gears make it possible to keep the engine’s RPM’s (revolutions per minute) within an economical and safe range to promote better gas mileage and decrease wear on engine components.
Transmissions,speed increaser gearbox coupled with different gear ratios also make it possible to accelerate and achieve the higher top speeds seen in modern cars.
Now that you have some general background knowledge about gearbox transmissions, you can select which type of transmission will best fit your needs.
