when i'm at the drag stip and my car shifts into 3rd gear at about 70 mph it makes a strange noise. the first time i heard it i thought it was my tires chirping (i wish, it's stock). After i thought about it for i while i think it might sound like metal on metal. Anyways, when it happens it feels like it looses a whole lot of power for just a fraction of a second. does anybody know what it could be and if it's a bad thing? (my car is an automatic)

Are you sure it's not belt slip? A common f-body problem is the accessories have a hard time slowing down on a gear shift, the belt gets worked pretty hard and may screech. One way to find out is to remove the belt and take a quick trip down the block and see if that is the culprit. Don't try to drive far, the battery won't get recharged. If it is the belt, clean all the pulleys really well and try a new belt. Also check the range gauge on the tensioner. The arrow molded into the case should point between the two hash marks on the base. If that is too loose, that can cause the problem as well.
