Audi Auto Trans Mount - Genuine Audi 4K0399156A

Product Information

A transmission mount is a crucial component in a vehicle that secures the transmission to the vehicle’s chassis. It typically consists of a metal frame with rubber or polyurethane insulation. Its main function is to hold the transmission in place, reduce vibrations, and prevent excessive movement during operation. The rubber or polyurethane part helps absorb vibrations and shocks from the engine and road, improving ride quality and protecting the transmission.

• Clunking or Banging Noises: When the transmission mount is damaged, you may hear clunking or banging sounds during gear changes or when accelerating/decelerating.
• Excessive Vibrations: One of the primary signs of a failing transmission mount is increased vibrations or rattling, especially when the vehicle is idling or during acceleration. As the mount loses its ability to absorb shocks, vibrations can be felt inside the cabin.
• Engine Misalignment: As the transmission mount also plays a role in maintaining proper alignment between the engine and transmission, a broken mount can cause misalignment issues, especially in front wheel drive configurations.

About Genuine Audi

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Audi parts box and find an OEM branded part inside, simply with the addition of an Audi logo.
