Automatic transmission (AT)
* Shifts gears automatically depending on speed and engine load.
* Convenient for driving in urban conditions and on steep climbs.
* More expensive to maintain and repair compared to manual transmission.
* May be less fuel efficient than manual transmission.
Semi-automatic transmission (automatic transmission with manual mode)
* Combines the capabilities of automatic and manual transmission.
* Shifts gears automatically, but also allows the driver to change gears manually.
* Provides more control over the vehicle than a conventional automatic transmission.
* May be more fuel efficient than a conventional automatic transmission.
Scope of application
* Automatic transmissions are best suited for novice drivers, as well as for driving in urban environments with frequent stops and starts. They are convenient for overcoming steep climbs and traveling long distances.
* Automatic transmissions with manual mode are a good option for drivers who want to combine the convenience of an automatic transmission with the option of manual control. They are suitable for mixed driving conditions where a balance between comfort and control is required.
Advantages and Disadvantages
