Used OEM Audi transmission mount with part number 4M0399118K. This genuine mount, also known as a motor mount or engine mount, was removed from a donor vehicle. It serves to dampen vibration and secure the transmission to the chassis, reducing drivetrain movement during acceleration and deceleration. A worn mount can cause excessive shudder, clunking noises on shifting, or misalignment of the driveline. This specific mount is designed for Audi Q7, RS Q7, SQ7, and SQ8 models with MHEV or PHEV 2.0L, 3.0L, or 4.0L turbocharged engines.
