A manual gearbox, also known as a manual transmission, is a type of vehicle transmission that requires the driver to manually shift 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 engages and disengages the engine from the wheels by pressing the clutch pedal, allowing them to select the appropriate gear for the driving conditions. This type of transmission is commonly found in cars, motorcycles, and trucks, offering a different driving experience compared to automatic transmissions.
