When I start up from stopped I get a quick screech (almost like a tire chirp - maybe it is) when I let the clutch out. Sometims a little shudder also. Car supposedly has an ATC clutch. Shifting once moving is fine. No sign of slippage. Is this normal for this clutch or is getting time for a new one?

Clutch's usually don't make noise when they are slipping they just slip.You have to find out what clutch is in your car,if it's a 4 puck disc it will shutter a little bit when you take off at a start.The throw out bearing will make noise,but usually when your foot is off the clutch pedal.

Pilot bearing?

Two possibilities that come to my mind are:
a) Throw-out bearing - which may or may not be bad, sometimes they just make a little noise with light contact on the Pressure Plate fingers.
b) You need to grease the contact point of the Slave Cylinder piston on the clutch fork.

Thanks guys. The noise comes just as my foot comes off the clutch pedal and only when starting up. It would seem that the throw out bearing would make noise when I have the pedal depressed and there is pressure on it. Am I missing something? Is there a way to lube the pilot bearing without tearing the whole thing apart?

FWIW, mine makes the same noise: screech and a bit of judder when moving off. Obviously my friends assume I can't manage a clutch [blush] but seems like I'm not the only one - interested in any ideas on the cause!

Yes the throw out bearing can make noise when your foot is off the clutch pedal.The reason why it makes noise when your foot is off the pedal is,the fork that push's the throw out bearing only grabs the outside of the bearing.When there is no pressure on the bearing(foot off clutch)it free spins and you can hear the bearing outer ring binding (chirping).When you push the clutch down the pressure keeps the bearing (outer bearing ring)from wobbling around,and thats why the noise goes away.These throw out bearings are diff.then wheel bearing's.Wheel bearings usually make more noise when you put pressure on them!

Usually when the pilot bearing goes bad you should be able to hear it all the time (usually).That doesn't mean it's not bad.

For what it's worth,mine makes the same noise and that's because I have a three year old clutch in my car.I will change it once it starts to slip.

I hope this helps you out a little!

Thanks Bob - helps with peace of mind. I was kind of worried that something was going to let go in a big way. If the chirp lasted longer people might think I had enough power under the hood to lay down some rubber!
