Manual Transmission
Modern cars with manual transmissions usually have four or five forward speeds and one reverse, as well as a neutral position.
The gear lever, operated by the driver, is connected to a series of selector rods in the top or side of the gearbox.
The most popular design is the constant-mesh gearbox. It has three shafts: the input shaft, the layshaft and the mainshaft, which run in bearings in the gearbox casing.
The engine drives the input shaft, which drives the layshaft. The layshaft rotates the gears on the mainshaft, but these rotate freely until they are locked by means of the synchromesh device.
It is the synchromesh device which is operated by the driver, through a selector rod with a fork on it which moves the synchromesh to engage the gear
Clutch
The clutch , when engaged allows the engine's power to be interrupted from reaching the gearbox in order to select a new gear
