This left-side Audi transmission mount bracket (OEM 4E0399113AA, also replaces 4E0399113M) is a used genuine OE part removed from a donor vehicle. The bracket secures the transmission to the subframe, helping isolate driveline noise and vibration. Over time, worn bushings or a bent bracket can cause excess movement, clunking during shifts, or drivetrain shudder. Fits Audi A8 Quattro and S8 with 4.2L V8, 5.2L V10, or 6.0L W12 engines.
