hey guys to make a long story short when i rev my car up with the trans in neutral there is no vibration when reved up, when i put the car in gear but the clutch pedal down there is a vibration at about 3500 rpm and it gets worse the higher it goes. does this sound like something is loose in the trans, it is a t5z box. thanks for any input

Sounds like the clutch has something loose. With the transmission in neutral and the clutch out, the input shaft is still spinning. If you put it in gear the input shaft will still spin if the clutch is let out. If it's in gear with the clutch pushed in, nothing should be spinning in the transmission until you start to move, then everything will spin.
Ergo. . .does it vibrate going down the road at 3500 rpm or is it just while sitting still reving with the clutch pushed in? If pushing in the clutch causes it, I'd say the clutch is the culprit.
