Detailed Description
This MasterPro transmission mount is engineered for rear-right installation on Cadillac DeVille, Fleetwood, Commercial Chassis, and 60 Special models listed in the fitment data.

It is a direct OE-style replacement for service work where the original mount has deteriorated, separated, or lost support.

What It Helps Fix

- Rear-right transmission support wear on listed Cadillac applications
Installation Notes and Tips
Verify the rear-right position and match the vehicle application before installation. Inspect the surrounding brackets and fasteners for wear or damage, since mounting hardware and a mounting bracket are not included. Confirm that the replacement mount matches the original stud layout and service configuration before tightening to specification.
