This polyurethane trans mount insert is designed to be pressed into the OEM transmission mount for a 2004-2006 Pontiac GTO and 2001-2005 Holden Monaro. It will fit both automatic and manual trans mounts.
The trans mount insert is made from high grade polyurethane with an 80A hardness. It was molded to perfectly match the inside of a brand new OEM transmission mount. It will significantly stiffen the OEM trans mount creating less slop in the driveline. It will improve shifting, prevent sagging, and drastically extend the life of the OEM mount.
