Detailed Product Overview

Westar EM-2664 is an automatic transmission mount for rear right placement on select Buick and Oldsmobile vehicles. It is intended for drivers and repair shops servicing 1986 Buick LeSabre, 1985-1986 Oldsmobile 98, and 1986 Oldsmobile Delta 88 models that require the 2nd design mount configuration. The part number EM-2664 is also cross-referenced to common aftermarket listings for the same application, including Anchor 2664 and DEA Products A2664.

Westar focuses on using materials matched to the application and a finish that helps the mount hold up in daily use. If you are replacing a deteriorated transmission mount on a Buick LeSabre or Oldsmobile full-size platform, EM-2664 provides a direct replacement path without changing the original mounting location.

Common Problems This Part Can Address

• Excessive drivetrain movement under acceleration or load
• Vibration transferred into the cabin from a worn transmission mount
• Clunking or shifting noise caused by mount deterioration
• Misalignment between the transmission and chassis mounting points
• Visible cracking, separation, or collapse of the original mount

Installation Notes and Tips

Verify the rear right position and 2nd design configuration before ordering. On 1985-1986 Oldsmobile 98 applications, confirm the 4-stud note listed in the fitment data. Inspect adjacent drivetrain mounts and brackets during replacement so the new mount is installed against sound supporting components. Compare the original mount shape and bolt pattern to EM-2664 before final installation.
