There is a clicking noise coming from my transmission when the car is in neutral, or in gear with the clutch pushed in. It only makes the clicking noise when the car is moving, and it gets louder with speed. But it doesn't make any noise when it's in gear or under acceleration. The transmission feels fine. I changed the tranny fluid with Gm Synchromesh, and the transmission bolt with a skunk 2 magnetic one, last weekend and it has made the noise since then. It never made the noise before and it made it as soon as I drove the car after changing the fluid and bolt. The transmission is from a 1998 gsr. Any ideas what this noise could possibly be? Thank You
