The Audi transmission mount bracket / cross member (OEM 8K0399263K) is a used genuine part, also superseding 8K0399263AD. This structural support secures the transmission to the chassis, reducing drivetrain movement. When the mount bracket fatigues or cracks, symptoms include clunking during acceleration or deceleration, increased vibration, and misalignment of the driveline. Engine fits include the 2.0L EA888 turbo four and 3.0L supercharged V6.
