Automatic transmission (AT)
* Shifts gears automatically based on engine speed and load data.
*Uses torque converter for smooth gear shifting.
* Usually has a fixed number of gears (usually from 4 to 10).
* Provides a smooth and comfortable driving experience, but may be less fuel efficient and responsive than other transmission options.
Double clutch transmission (DSG/DCT)
*A type of automatic transmission that uses two clutches for quick and efficient gear changes.
* Has two transmissions, each using a separate clutch: one for odd gears and one for even gears.
* Gear changes occur very quickly and smoothly.
*More fuel efficient and responsive than a traditional automatic transmission, but may be more expensive.
Robotic manual transmission (RMG)
* Combination of manual and automatic transmissions.
*Uses a mechanical clutch and a computerized system that controls gear changes.
*Typically cheaper to manufacture than automatic transmissions, but less smooth when changing gears.
* Can be configured in automatic or manual gear shift modes.
CVT (CVT)
* A type of transmission that uses belts or chains located between two pulleys to change the gear ratio.
* Provides smooth and continuous gear shifting, eliminating the jerking associated with manual transmissions.
*More fuel efficient than traditional automatic transmissions, but may be less responsive to hard acceleration.
