No more messing with RTV
Upgrading the shifter on your 2011-2014 MustangMT-82 Transmission can result in increased gear noise from the shifter. The solution? A Silicone Shifter Gasket to ease installation and reduce noise. Pre-Cut to seal the shifter base to the transmission and fit between the shifter handle, these gaskets are 1/16th" thick and are reusable. Adding these to your shifter will reduce interior noise while maintaining a positive shifter feel, making gear changes.
If your gaskets are deforming when tightened or pushing out then you are over tightening the shifter bolts.
