    About a month ago I purchased a 95 two door tahoe with the nv3500 manual tranny in it. I have noticed a whining/rattling sound when the truck is neutral at a stop with the clutch out. When you press in the clutch the sound goes away? It also grinds going into reverse if you don't sit for a couple of seconds with the clutch pressed in. Any ideas? :confused:

    sounds like input bearing and syncros are worn . but cant recall if the nv3500 are synced in revers.

    For the grinding, just shift into 2nd, THEN to reverse, without letting out the cluth in between. It shouldn't grind then. :)

    Thanks, some said it was the throwout bearing, but I thought that was only when the clutch was pressed in. As far as the reverse thing, it isn't that bad just got to work around it.

    correct only when pressure is on it will that make much noise.
