A manual gearbox, also known as a manual transmission, is a type of vehicle transmission that requires the driver to manually change gears using a clutch pedal and gear stick. This system allows for greater control over the vehicle's power and speed, making it popular among driving enthusiasts. In a manual gearbox, the driver must engage the clutch to disconnect the engine from the wheels before shifting gears. This process can enhance fuel efficiency and performance, as the driver can select the optimal gear for different driving conditions. Many sports cars and motorcycles utilize manual gearboxes for this reason.
