Product Details

This automatic transmission mount is engineered for Lexus RX300 models from 1999 through 2003 and is intended to replace a worn or damaged factory mount. Pioneer Cables 629073 uses a durable metal housing and bonded rubber construction to help maintain drivetrain alignment and reduce movement under load. This part cross-references Anchor 9073 for the same application.

Common Issues It Can Help Address

• Excessive drivetrain vibration felt in the cabin
• Clunking or shifting movement during acceleration or gear changes
• Visible cracking, separation, or collapse in the original mount
• Transmission movement caused by a weakened support point
• Noise transfer from the drivetrain into the chassis

Installation Notes

Verify the vehicle application before installation by matching the year, make, and model. Inspect adjacent mounts and drivetrain components for wear, since a damaged support can place added stress on surrounding parts. Confirm the mount orientation and mounting points against the original part before final tightening.

Quality Assurance

Pioneer Mounts use the Sure-Fit System, which relies on vehicle-specific application testing to improve fit consistency. The mount housing is manufactured from high-grade metal with a corrosion-resistant finish, and the rubber element is bonded for application-specific vibration control.
