Construction and operating characteristics

The gearbox belongs to a modern family of automatic transmissions designed for smooth gear shifting, efficient use of petrol engine power, and reduction of mechanical losses. The applied design enables:

• efficient acceleration without jerking,
• maintaining optimal engine RPM in typical road conditions,
• comfortable driving in the city and on the highway thanks to appropriately selected gear ratios.

Automatic gear control allows the driver to focus on driving, while the gearbox system independently selects gears depending on load, speed, and driving style.

Application in the BMW F20 drivetrain

In BMW F20 models with the N13 petrol engine, this automatic gearbox is responsible for transferring power to the wheels while maintaining the brand's characteristic dynamics. Proper tuning with the powertrain ensures:

• stable starting and predictable throttle response,
• consistent operation with driver assistance systems,
• maintenance of the factory handling character typical of BMW.

For users who expect to maintain original driving properties after replacing the transmission, choosing a gearbox from the same design family is crucial.
