Tame drivetrain vibration and keep your transmission properly supported with the Anchor transmission mount 3525, built for the LEFT position. It's a direct-fit replacement for many vehicles, among them the 2018-2026 Chevrolet Traverse, 2020-2026 GMC Acadia, and 2018-2027 Buick Enclave — see the "Vehicles it fits" section for the full list and engine-level fitment.
This mount helps support and locate the transmission while its rubber isolates and dampens vibration to limit movement felt in the cabin. If a worn or separated original mount is behind clunks on acceleration, shifting, or vibration at idle, this unit is designed to replace it and help return that isolation.
- Engineered to OE standards: designed using CAD/CAM engineering for consistent quality.
- Natural and Styrene Butadiene rubber: resists wear and stays stable as it ages.
- Chemlock® bonding agent: creates a superior rubber-to-metal bond.
- Application-tuned rubber: molded to specific Durometer (hardness) measurements based on vehicle requirements.
Any included fasteners are hardened steel with heat-treated Grade 5 bolts; consult the vehicle service information for the correct fasteners and whether they may be reused.
