vibration in clutch

After a few 2500 rpm clutch dumps (2 or 3). My tranny likes to vibrate when taking off in 1st and reverse. At first I just thought my clutch was on its way out, which really doesn't bother me as much as you think it should. But now that I drive it a little more I'm not so sure. The dern thing is still strong as ever. 1st doesn't slip, second and third still bite the tires and 6th doesn't slip at all. So what's up? I know its not slipping. But why is it vibrating and shaking the car when I let it out? Its weird how this actually bothers me more then a burnt clutch, unless these are the signs of one going out....

try bleeding all the clutch fluid and filling it with fresh fluid. is it black and dark and dirty?? also try to change out our tranny fluid drain all that out and fill with some good synthetic or regular gear oil and mayb an additive if you would like. is it vibrating the car like hell when you take off??? it might just be the slave cylinder hesitating to release when you let it out, have you tried to let it out fast without spinning??? or does it do it only when you let it out slow kind of like the clutch is hesitating to grab. check your slave and master cylinders for leaks also!

everything is full, tranny fluid was swapped to dexron III, I believe Valvoline. I haven't changed the clutch fluid, but it looks no darker then the brake fluid in my reservoir, which isn't bad. It does only do it when let out slowly. Also I can feel a vibration at about 2000 rpm, that was not there before. Something is about to go, I just can't figure out what. I don't really like waiting until it breaks if you know what I mean.
