Shifter bushing replacements for 915 transmission

Wednesday 11/19/2025 | 1985 | 911 Carrera | Other

I replaced my OEM shifter with a short shift kit a number of years ago. Shifting is has gotten extremely sloppy now and suspect my bushings are completely worn. I see online there are a large variety of materials used in replacement bushings. I would presume my coupler is fine and I only need to replace the bushings there as well. Do you have any recommendations as far as the type of bushings I should consider? Thanks, Jeffrey ...
