  • Noises from transmission

    I just did the A4 to M5 swap. When the car is sitting still in netrual it makes a grinding type noise, it reminds me of a bad supercharger cupler but quite a bit louder. The second i put the clutch petal down the noise stops. Also when I put the car in gear and go to move, just before the clutch is fully released it sounds like the clutch is rubbing? I have driven quite a few stick shift cars and have never heard that before. Any insight?

    ok, after doing some research I think the grinding noise when my car in neutral is a bad throw out bearing. as for the rubbing sound when i am shifting into gear and letting the clutch out, i dont know.

      Did you put grease on the input shaft/pilot bushing?......I'm told these should be assembled dry or just a few drops of oil, but no grease, as it plugs up the self oiling feature of the sintered bronze "oilite" bushing.

        That is a yes to grease on the pilot bearing. My friends dad who has been working for GM over 20 years told us to.

        That is the only place i put grease.

          you should not grease the pilot bearing, it should only be dipped in some oil

          it does sound like a messed up TO bearing though, i would suggest when you replace it, to replace the pilot bearing also

          from what i know, our pilot bearings (or bushings, whatever you call it) are self oiled and grease will mess it up
