This used genuine OEM Audi transmission cross frame / mount bracket, part number 4E0399231N (also replaces 4E0399231S), supports the transmission and maintains drivetrain alignment. Designed for Audi A8 and S8 models equipped with naturally aspirated 4.2L V8, 5.2L V10, or 6.0L W12 engines, this bracket plays a key role in minimizing vibration and ensuring proper mounting. A worn unit can cause driveline clunking or misalignment.
