When a gearbox is employed between the engine and road wheels this reduces the speed of rotation at the wheels to more manageable levels. If it was possible to connect your engine directly to the driven wheels, these RPMs would see the wheels turning at 75mph or so - even when ‘idling’ at 1,000rpm without you touching the accelerator pedal. Namely, that its internal components must typically spin at anything between 1,000 and 7,000 revolutions per minute (RPM), in order to keep running. To understand why a car needs gears, you have to understand one of the basic principles of the internal combustion engine. The relative position of each gear is typically marked on the top of the gear lever, and the lever itself is spring-loaded so when the gearbox is in neutral (meaning no gear is engaged) the lever rests between third and fourth gear slots in the middle of its gate. Apart from a clutch pedal, the other unique feature of a manual transmission is a gear-lever that the driver must move through a slotted ‘gate’ to select and subsequently engage the desired gears.
