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
