Detailed Description

Pioneer Cables 622321 is engineered as a replacement manual transmission mount for Pontiac Catalina and Pontiac Bonneville models listed in the fitment data. The mount uses a durable metal housing with a corrosion-resistant finish, paired with a bonded rubber element formulated for the specific application to help absorb drivetrain vibration and support stable transmission positioning.
