The automobile transmission system comprises several components that together transmit the rotatory motion of the engine's crankshaft gradually and efficiently to the wheels.
Mounted on the top of the engine it converts the engine's combustible power to momentum while setting the wheels in motion. It converts speed and momentum into power and puts the vehicle in motion while reducing the pressure from the engine to make it function efficiently. It transmits the power from the engine to the wheels along with the driveshaft and axle that helps you to drive the car better.
The gears ratios are either selected by the driver or change automatically. In a car with a manual transmission, pressing the clutch will bridge the engine and the transmission, helping you to change gears. In the automatic gearbox, the change takes place automatically.
The transmission system comprises the following parts.
A clutch disconnects the engine from the wheels. The rotatory movement of the crankshaft does not reach the wheel with the intrusion of the clutch. Transferring motion gradually puts the vehicle in motion following the principles of fiction.
it consists of a pair of gearwheels that transmit the available motion from the crankshaft, through the clutch at a different speed. It provides the necessary connection between the engine and the roadwheels. This connection adapts itself to the different condition the vehicle faces while in motion. The torque output will be inversely proportional to the speed. (See Used Gearbox for more information)
This component transfers motion from the gearbox to the differential end. The distance between the two is bridged by a thin and long shaft that connects them. It should be lightweight and should not be misaligned or sag with good torsional strength. It should meet the design specification.
The overall length of the propeller shaft also called the driveshaft, or a driveline shaft is not too much. (See Used Propeller Shaft for more information)
This is a system of gears that allows different wheels on the same axle to rotate at different speeds when the car is turning. Through wheel and pinion arrangement this action is performed by the differential. The inner and outer wheel speed variation when the vehicle is taking a return is also performed by the differential.

It is an axle through which power is transmitted to the wheel. Generally, it is transferred to the rear axle but in some vehicles, can be transferred to both the front and rear axles
. This results in the motion being transferred to the road wheel. The friction between the wheels and the road helps the vehicle to move.
