Purpose and technical specifications

The presented automatic gearbox has been developed to work with the 3.0 TFSI petrol engine in a Quattro configuration, ensuring appropriate gear ratios for both dynamic and comfortable driving. The automatic transmission design is adapted to the high loads typical of the S4 version, with an emphasis on smooth gear shifts, stability during acceleration, and predictable behavior during highway driving.

The automatic transmission in this Audi model is responsible for:

• precise torque distribution to all wheels in the Quattro system,
• maintaining optimal engine RPM across the full speed range,
• reducing jerking during gear changes, which improves driving comfort,
• effective utilization of the TFSI petrol engine's performance characteristics.

Benefits of using an original automatic gearbox

Using an original automatic gearbox dedicated to the Audi S4 B8 allows for maintaining the factory performance parameters of the drivetrain. Proper tuning of gear ratios with the petrol engine and Quattro drive translates into:

• consistent acceleration characteristics – the gearbox keeps the engine in the optimal RPM range,
• stable vehicle behavior at higher speeds and during overtaking,
• better integration with the vehicle's factory electronic systems,
• reduced risk of issues resulting from the installation of an incompatible transmission.

For the user, this means predictable throttle response, proper operation of driving modes, and maintaining the car's character in accordance with the manufacturer's specifications.

Condition, verification, and fitment

The offered gearbox belongs to the group of used OEM components, which allows for combining a favorable purchase cost with the preservation of original technical specifications. Before installation, a standard workshop procedure is recommended: checking for leaks, verifying mounting points, inspecting connectors, and preparing the oil system in accordance with the vehicle manufacturer's guidelines.

To correctly match the transmission to a specific Audi S4 B8 unit, it is worth verifying the compatibility of the gearbox codes, fuel type, and automatic transmission type with the vehicle's data. This helps avoid problems with control compatibility, mounting, and software.

Operation and service recommendations

Automatic gearboxes in high-power cars such as the Audi S4 B8 3.0 TFSI Quattro require regular maintenance. It is crucial to use the appropriate transmission fluid, check its level, and perform periodic changes according to the service schedule. Attention to these elements contributes to:

• extending the service life of the transmission,
• maintaining smooth gear shifting,
• reducing the risk of overheating and clutch slippage,
• stable operation in both automatic and manual modes (if present in the given configuration).
