Manual Transmission is a system used in cars to control gear changes manually by the driver, without automatic gear-shifting mechanisms. It is often referred to as manual or stick shift, and it is typically paired with a clutch that is used to disengage power transmission between the engine and the gears when the driver shifts. Manual Transmission systems often have multiple gears (such as 5 or 6 gears) that the driver must shift through using controls within the car.
