Purpose and compatibility

The presented gearbox has been designed to work with the 1.8 TFSI petrol engine with the CDHB code in the Audi A4 B8. The automatic design ensures smooth gear shifting, matched to the characteristics of the power unit, which translates into stable acceleration and comfortable driving in both city traffic and on the highway.

By maintaining the factory configuration of the drivetrain, installing this gearbox in place of a damaged unit allows you to retain the vehicle's original operating parameters without the need for control modifications or the adaptation of non-standard solutions.

Technical and functional characteristics

The automatic transmission design provides:

• sequential gear selection by the transmission control unit,
• optimized cooperation with the petrol engine in terms of dynamics and fuel consumption,
• convenient operation in urban conditions, without the need for manual gear shifting,
• stable torque transmission across the full load range.

This solution is particularly beneficial for drivers who expect driving comfort, predictable throttle response, and consistent drivetrain operation in daily use.

Condition, verification, and advantages of purchasing a used gearbox

The offered gearbox comes from the secondary market, which allows for significant repair cost savings compared to purchasing a brand-new component or undergoing a full refurbishment. A used automatic transmission, selected according to the model and fuel type designation, represents a reasonable compromise between price and functionality, especially for vehicles used on a daily basis.

Before installation, a standard service procedure is recommended, including checking for leaks, verifying the condition of the transmission fluid, and performing a gearbox adaptation in accordance with the vehicle manufacturer's procedures. This approach increases the chances of long-term and stable drivetrain operation after replacement.
