Car Transmission Cutaway
A transmission is a mechanical device that transmits power from one part of a machine to another. In a car, the transmission transfers power from the engine to the wheels. This allows the car to move forward and backward, and to change speed.
There are many different types of transmissions, but the most common type is the manual transmission. A manual transmission has a set of gears that are shifted manually by the driver. The driver must select the correct gear for the speed and load conditions of the car.
Automatic transmissions are also available. An automatic transmission shifts gears automatically, based on the speed and load conditions of the car. This makes driving easier, but it can be less efficient than a manual transmission.

Input Shaft
The input shaft is the shaft that receives power from the engine. It is connected to the clutch, which allows the driver to engage and disengage the transmission.
Counter Shaft
The counter shaft is the shaft that carries the gears. It is connected to the input shaft by a set of gears, and to the output shaft by another set of gears.
Output Shaft
The output shaft is the shaft that transmits power to the wheels. It is connected to the counter shaft by a set of gears.
Gears
The gears are the components of the transmission that transmit power from the input shaft to the output shaft. They are arranged in a set of pairs, with each pair consisting of one gear on the input shaft and one gear on the counter shaft.
The different pairs of gears have different ratios, which allow the transmission to change the speed and torque of the output shaft.
Clutch
The clutch is a component of the transmission that allows the driver to engage and disengage the transmission. When the clutch is engaged, the input shaft is connected to the counter shaft, and power can flow from the engine to the wheels.
When the clutch is disengaged, the input shaft is disconnected from the counter shaft, and power cannot flow from the engine to the wheels.
