Mine did it during start up Saturday AM in VT 14F. Sunday AM didn't do it 9F. Today back home it did it after start up, 17F.
If you guy's think this is annoying wait until the pressure plate howls when you let the clutch out in first gear....sometimes. Does it all year long. I used to think it was the TOB but I've had 3 of them in there since the Spec clutch was installed over 60,000 miles ago. But that's a topic for a different thread.
