I noticed today as I was sitting at a stoplight with the windows down, that if I put the truck in neutral and let off the clutch, I can hear a slight noise from the tranny or clutch area. I just got a new clutch about 30k ago so I don't think that would be it...is this normal or should I be looking into something?

Edit: it's almost like the sound when you engage a PTO, but not nearly as loud. I have to stick my head out the window to really hear it.

 

Might just be clutch noise. My dad's vette makes a little noise when the clutch pedal is out while sitting at idle. Sounds like pebbles in a can almost.

 

most likely a throwout bearing, some can get a little "chatty". did they put new bearing in when replaced? i wouldn't worry about it though, unless it really starts singin' loud

 

Yeah they replaced the bearing with the new clutch, I figured it was just some random noise so im not real worried...thanks guys!
