Puzzling transmission noise

I been getting this wierd chirping chattering noise whem Iam decelerating starting around 3k down to 2.2k that seems to be coming from the bellhousing area. If I give it a slight amount of gas it will quit. The wierd thing is that ocasionally it will do this when accelerating at the same rpm range and quits when i release the gas. Also once in a great while if I rev the engine in neutral it will do it in the same rpm range but not as loud. It's mostly noticable when decelerating. I have had noisey tob's but none sounded like this. My transmission does have 120000 miles on it

The clutch has less than 10000 miles. It dosen't happen at idle and it dosen't get quiter or louder when slighlly depressing the clutch pedel. happens only at certain rpms mostly when decelerating then if i give it a little gas and it goes away. But the clutch Iam using was already on the back of a 2002 engine assembly that had zero miles on it. It was complete from Tb to the oil pan including all accesories even had a belt, wiring harness and oil in it. The tob has about 15000 miles on it because i put a king cobra clutch kit on the car before the engine went which came with the tob. The cobra clutch would not work on the new engine because of the different cranks and flywheels produced for the two different years.
