Purpose and technical specifications

The presented automatic transmission has been designed to work with the 3.0 TFSI petrol engine in a quattro configuration, typical for Audi S4 B8 and S5 8T models. The automatic design ensures smooth gear shifting, stable torque transfer, and consistency with factory drivetrain and traction control systems.

As an OEM Audi component, the transmission retains original mounting points, geometry, and operating logic, which facilitates installation and integration with the existing electrical system and transmission cooling system. This makes it a particularly beneficial solution for post-failure repairs, swaps, or comprehensive drivetrain overhauls.

Application in the Audi S4 B8 / S5 8T drivetrain

The automatic transmission in this model plays a key role in managing the power of the 3.0 TFSI engine while working in tandem with the quattro all-wheel-drive system. It is responsible for:

• selecting gear ratios for optimal dynamics and driving comfort,
• proper interaction with electronic stability control systems,
• efficient power transfer to all wheels,
• maintaining appropriate operating parameters in both comfort and sport modes.

By maintaining factory specifications, installing this transmission allows for the restoration of the vehicle's original driving properties without the need to modify control units or wiring harnesses.

Benefits of choosing an original Audi automatic transmission

Choosing a used, original automatic transmission for the Audi S4 B8 / S5 8T offers a range of practical advantages:

• Factory compatibility – ensuring compliance with control software, the quattro drivetrain, and other powertrain components.
• Cost-effectiveness compared to a new part – a budget-friendly solution while retaining OEM construction.
• Consistency of operating parameters – gear-shifting characteristics consistent with the manufacturer's design, without the risks associated with aftermarket replacements.

This is particularly important in high-power vehicles, where precise cooperation between the transmission, engine, and all-wheel drive affects the durability of the entire system.

Selection, installation, and service aspects

Before installation, it is recommended to verify the compatibility of the transmission with the specific vehicle configuration (model year, engine version, drivetrain type), preferably based on vehicle data. During installation, it is worth paying attention to:

• proper bleeding and filling of the transmission oil system,
• checking the condition of drivetrain mounts and bushings,
• performing transmission adaptation in the control unit after installation, if required by the specific unit.

Thanks to the original design, the transmission works well with factory diagnostic and service procedures used within the Audi network.
