I have a 2002 s-10 with a 4cyl, 5spd trans. when the truck is idling, and the transmission is in neutral there is a slight gear chatter noise. sometimes it is louder than others, if you press in on the clutch it stops. the noise has always been there and the dealer tells me it is vibrations from the engine carrying into the input shaft. If this is true, is this going to create a problem later on. Or is this what the noise really is? Thanks for your help
