Throwout Bearing on 6-Speed

[WizardBlack]

Just bought my '08 4x4 with the manual tranny. It's a job#3. The dealer transferred it from a state away so it showed up with 300 miles on it. It's my first diesel, so I couldn't tell one rattle from another from the very beginning, but now I notice that most times when you pull up and stop, there is an extra rattle. It goes away when you press the clutch in and comes back about 50% of the time when you let the clutch out again.
I have been babying the thing. It only has 500 miles on it now. Supposedly the guy that drove it up is an older fellow (semi-retired service manager) that doesn't beat on stuff. It was sourced from a dealer in a record blizzard area so they probably didn't beat on it.
Anyone heard of this issue? Just a fluke or flaw in the build process?

i'd call it a fluke, a throw out bearing would be hard to "beat on"

That's kinda what I figured. I ended up taking it to the dealer and just got it back. I guess there is a bulletin out for the 6-speeds. They are supposed to make this noise, evidently. They checked everything out and left it at that, given the TSB.

I finally got under the truck and sprayed everything with lithium (bolts, threads, etc.) to help with corrosion. I was surprised to find that the tranny has a cooler on it.

Its probably just normal gear rollover. A lot of the heavy duty tranny's will make this noise. When the clutch is not enganged the input shaft will be spinning.

Mine made a knocking noise when I let the clutch out in neutral. That makes me suspect the front shaft bearings, but it seems to be intermittent. Also, I read that these sticks do have a transmission cooler.
