Quiet the driveline and keep your automatic transmission properly located with the Anchor Automatic Transmission Mount 9644, a rear transmission mount that drops in as a direct-fit replacement for the 1998-2000 Lexus GS400, 2001-2005 Lexus GS430, and 2002-2010 Lexus SC430 (see the Buyer's Guide tab for engine details). It helps support and locate the transmission while isolating vibration to limit movement and noise.
- Supports and dampens: cradles the rear of the transmission and absorbs vibration for smoother, quieter operation.
- Engineered to OE standards: designed using the latest CAD/CAM engineering process for consistent quality.
- Durable rubber: natural and Styrene Butadiene rubber that resists wear and stays stable as it ages for long service life.
- Strong bond: Chemlock® bonding agent for a superior rubber-to-metal bond, with rubber built to application-specific Durometer (hardness) measurements.
Any included fasteners are hardened steel with heat-treated Grade 5 bolts. Worn signs may include clunking on acceleration, deceleration, or shifting, vibration at idle, or cracked and separated rubber. If a failed transmission mount is the cause, this replaces it.
