    Weird Vibration- G240

    So over the past few days I've been getting a bad vibration from my transmission that can be felt in the clutch pedal and the shifter. It seems worse from 1.5k-3k and then disappears for the most part after 3.2k. During the vibration there's a definite humming sound coming from the transmission that's follows the engine's revs, the same goes for the vibration. It isn't speed or gear dependent, only rev. The sound doesn't go away when the clutch is depressed, nor the vibration.

    Background on the car:

    80k+ M42 (#2 M42 for this car, just refreshed 3 months ago)
    500k G240 (Resealed and fresh MTL)
    Remanufactured late model 325i starter
    New 323i flywheel
    New factory hardware for the clutch and pressure plate
    New Sachs 325i clutch and pressure plate
    New Sachs 325i throw out bearing
    New OEM 15mm pilot bearing
    New OEM center support bearing and pre-tensioned 10mm exactly
    Driveshaft balanced 1 year ago




    I'll post the pics from the single mass conversion a little later so it can be seen what I did to accomplish that.

      Possibly unbalanced flywheel?

          I would hope my brand new flywheel would be balanced from BMW. :|
