Okay, I just got back from my mechanics and he doesn't know what this is. When pushing the clutch in and driving down the road, we get a whining which leads me to think throw out bearing. But when the clutch is held in, no noise, only when the clutch pedal is moving. Also, it wont make any noise when sitting still and pushing in the clutch unless the revs are up there, then we can barely hear it. Its most noticeable when the car/drivetrain is moving. Any thoughts? The throwout is new Mitsu, Clutchnet clutch, and Jacks Trans, stock transfer case.
