Ok I got my 05 WRX last year and since then, when I am about 4500 rpms and take my foot off the gas, letting the car deccelerate, I hear a wierd noise that seems to be coming from the tranny. Kinda sounds like a rattle or grind. Very slight. When I accelerate/deccelerate normally in town, I have a tiny winding noise from the tranny. I took it to the subaru dealership I bought it from a few weeks after I got it. They said "oh well you're missing a few peices off the exhaust system so you need to buy those parts and have them installed before we can look at the tranny." That's basically what they told me. Anyways. It's been a year since I got it and I haven't had any problems with it. Just the same old noise. I would really appreciate the help!
