What is Transmission?
A transmission is a machine in a power transmission system that provides a controlled application of power. Often the term 5-speed transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque block conversions from a rotating power source to another device.

The term transmission properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts.

Different Types of Transmission are
1) Manual Transmission: In this transmission, gear changes require the driver to manually select the gears by operating a gear stick and clutch.

2) Automated Manual Transmission (AMT): It is similar to a manual transmission, except that the sensors and actuators perform the clutch work and shift gears. A car with an AMT does not have a clutch pedal; there's only the accelerator and brake pedal.

3) Intelligent Manual Transmission (iMT): it is a manual gearbox with gears and a gear lever that looks exactly similar to any manual gear lever. But the driving experience is more like an automatic car. iMT doesn't have a clutch but a brake and an accelerator pedal.

4) Automatic Transmission (AT): An automatic transmission (AT) is a multi-speed transmission used in motor vehicles that do not require any driver input to change forward gears under normal driving conditions.

5) Continuously Variable Transmission (CVT): A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide limited gear ratios in fixed steps.

6) Semi-Automatic Transmission: It is a multi-speed motor vehicle transmission where part of its operation is automated (typically the clutch actuation), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears.

7) Dual Clutch Transmission: A dual-clutch transmission (DCT) is a multi-speed vehicle transmission system that uses two separate clutches for odd and even gear sets.
