What are some clues that your throw out bearing is going out? My tranny make this grinding sound when I'm slowing down in a high gear but the second I push in the clutch or accelerate it's normal and no sounds. Any suggestions? Its a y8 tranny if that helps I got the y8 being that it's suppose to be the best of the SOHC tranny's with the steel shift fork and I never had any problem with it before until now and I had it for a year now.
