Vehicles with a manual transmission or transaxle have a clutch.It is between the engine and the transmission or transaxle.Before shifting,the driver depresses the clutch pedal.This disconnects the engine from the transmission or transaxle.Parts in these units may be damaged by trying to shift while under load.
In a car,you need a clutch because the engine spins all the time and the car wheels don't.In order for a car to stop without killing the engine,the wheels need to be disconnected from the engine somehow.The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them.
