• Metal-to-metal contact from a collapsed or cracked mount
• Fitment issues when replacing an aging manual transmission mount on GM rear-drive cars

Installation Notes

Verify the vehicle year, make, model, and transmission application before installation. Compare the original mount shape and mounting points to confirm the correct replacement for your specific GM platform. Because this part is listed for multiple models and years, checking the existing mount and drivetrain configuration before removal helps ensure a proper match.

Quality Assurance

Pioneer Mounts use the Sure-Fit System and application-specific testing to support consistent fitment. The mount housing is built from durable metal or aluminum, and the bonded rubber element is selected for the application to help isolate vibration and support long-term service in manual transmission use.
