Help! Clutch Problems!

[rippedforce85]

I tried posting a video but it is not cooperating. I will try to describe the problem the best I can. My CSC was replaced over the weekend at a local stealership (unfortunately). I also requested they replace the pilot bearing, but they apparently "forgot" according to the service advisor. I am experiencing a god awful screetching/howling/grinding noise when the clutch engages from a dead stop in first gear and reverse. As soon as the clutch engages and I start moving, the noise stops. No other problems besides this. No grinding gears, etc. Again, this only happens when taking off from a dead stop in first and second gear when the clutch is engaging. Also the noise doesn't occur all the time. I would say about 60-70% of the time. I put it on a friend of mines lift to let him listen to it and he said it was coming from the rear of the transmission and not the clutch area. From what I've read on the forum and other places, my guess is pilot bearing? Or could it be the trans itself? Please help!

*Update* I tried taking off in 2nd gear and the noise occurs also.
