(in a car) gear system that must be operated by hand (as opposed to an automatic transmission)
A manual transmission (also known as a stick shift, straight drive, or standard transmission) is a type of
transmission used in
automotive applications. Manual transmissions often feature a
driver-operated
clutch and a movable
gear selector. Most automobile manual transmissions allow the driver to select any gear at any time, but some, such as those commonly mounted on
motorcycles and some types of racing cars, only allow the driver to select the next-highest or next-lowest
gear ratio. This second type of transmission is sometimes called a sequential (manual) transmission.
