Hey everyone I have a MY00 2.5 coupe 5spd. I have a rattling/chirping sound from the following condition. When I'm accelerating @3700 - @4500 RPM, and then let off the gas, the sound occurs. If I depress the clutch pedal, the sound stops. This sound occurs most predominately in 3rd gear, a tad less in 2nd and 4th, and it doesn't seem that noticeable in 1st and 5th. The motor seems fine, and we're thinking it's a clutch/transmission problem?! I experience no other clutch/trans. problems. I'm taking it in to Subaru sometime this week, but I thought I would see if anyone has experienced or knows of this dilemma. Also, this sound was first noticed when leaving Death Valley a few weeks ago. I did some 4wd recommended roads on and banged some rocks around, but nothing too serious (or so I think). By the way, Death Valley offers some great terrain for IMPREZAS!!! Any thoughts would be appreciated! Thanks!
