Keep the rear of the transmission planted and quiet with the Anchor transmission mount 3543, a direct-fit rear automatic transmission mount for the 2017-2019 Chevrolet Silverado 2500 HD, 2017-2019 Chevrolet Silverado 3500 HD, 2017-2019 GMC Sierra 2500 HD, and 2017-2019 GMC Sierra 3500 HD. This Anchor automatic transmission mount supports the transmission and dampens vibration, helping locate the powertrain and isolate the driveline from the chassis.

  • Supports and isolates: Holds the rear of the transmission in position while damping vibration for a smoother, quieter driveline.
  • Engineered to OE standards: Designed to OE standards using a CAD/CAM engineering process for consistency and quality.
  • Durable rubber: Built from natural and Styrene Butadiene rubber that resists wear and stays stable as it ages for long service life; rubber is manufactured to a specific durometer (hardness) based on vehicle application requirements.
  • Strong bond and hardware: A Chemlock® bonding agent creates a superior rubber-to-metal bond, and any included fasteners are hardened, heat-treated Grade 5 steel bolts.

Signs this mount may need replacing include vibration at idle, a clunk on acceleration, deceleration, or shifting, and cracked or separated rubber.
