Product Description

This MasterPro transmission mount is engineered as an OE replacement for vehicles that need a stable connection between the transmission and chassis. The steel bracket and steel mount housing provide a rigid foundation, while the rubber bushing and solid cushion design help isolate drivetrain movement. If you are replacing a worn automatic transmission mount on a Pontiac Grand LeMans, Chevrolet Monza, or Oldsmobile Cutlass, A2531 offers a direct replacement format that matches the original equipment specification level.

Common Problems This Part Can Address

• Excessive drivetrain movement under load
• Clunking or shifting noise from a worn mount
• Vibration transferred into the cabin
• Transmission misalignment caused by a deteriorated mount
• Cracked or separated rubber in the original mount

Installation Notes

Verify transmission and chassis mounting points before installation. This mount includes the mounting bracket, but mounting hardware is not included. Confirm the vehicle application by year, make, model, and transmission configuration before ordering, especially for Pontiac Sunbird, Pontiac Phoenix, and Oldsmobile Starfire applications.

Quality Assurance

MasterPro A2531 is listed as meeting or exceeding original equipment manufacturer specifications and is built as a standard replacement part for consistent fit and function.
