Detailed Description

Pioneer Cables 622766 is a replacement automatic transmission mount bushing designed for vehicles that need stable transmission support and controlled isolation from road and powertrain vibration. The housing uses high-grade metal with a corrosion-resistant finish, while the bonded rubber element is selected for the specific application to help maintain proper drivetrain positioning and reduce harshness. This part is a practical choice for drivers servicing a Pontiac Grand Am transmission mount bushing, as well as Buick Skylark and Oldsmobile Cutlass Calais applications. This part cross-references OSC 3058 for the same application.

What It Helps Address

• Excessive vibration felt through the floor or drivetrain
• Worn or deteriorated transmission mount support
• Movement or shifting of the transmission under load
