Peculiarities
* Torque Converter: Provides smooth gear shifting and reduced vibration.
* Planetary gear sets: provide different gear ratios.
* Clutches and steel discs: transmit torque between planetary gears.
* Valve block: controls the fluid flow in the gearbox, changing gears.
*Electronic control unit (ECU): controls transmission operation, optimizing gear changes for various driving conditions.
Advantages
* Smooth gear shifting
* Improved fuel economy
* Improved performance
* Reduce noise and vibration
Flaws
*Higher cost than manual transmissions
* More complex design requiring regular maintenance
*Potentially reduced fuel economy during aggressive driving
