A manual transmission requires the driver to operate the gear stick and clutch in order to change gears (unlike an automatic transmission or semi-automatic transmission, where one (typically the clutch) or both of these functions are automated).
Most manual transmissions for cars allow the driver to select any gear ratio at any time, for example shifting from 2nd to 4th gear, or 5th to 3rd gear.
However, sequential manual transmissions, which are commonly used in motorcycles and racing cars, only allow the driver to select the next-higher or next-lower gear.In this video we will see how automobile manual transmission operatesIf you like this video, please click the like button and make it reach more people.
In a vehicle with a manual transmission, the flywheel is attached to the engine’s crankshaft, therefore rotating at engine speed. A clutch sits between the flywheel and the transmission input shaft, controlling whether the transmission is connected to the engine clutch engaged- the clutch pedal is not being pressed or not connected to the engine clutch disengaged- the clutch pedal is being pressed down.//wikipedia
