I have a 2004 wrangler x 4.0 manual trans. (I know my username says 98. I upgraded) but When I first got it. There was a whining noise from the tranny that would go away when the clutch was pushed in, I brought it to the shop and they replaced the clutch, pilot bearing and throwout bearing, also the clutch bearing. They put it back together and the noise was still there. They are now going to try an input shaft. Any ideas??
