I have a 2000 Civic Si. I purchased it new and have kept up with the maintinence. Recently I noticed that when I depress the clutch pedal and when I release it, a horrible squeaking sound is made. I've checked the fluid levels and all of those were normal. It sounds like it may be coming from the transmission area when the hood is raised and the clutch is depressed. It seems to be driving okay, I haven't noticed a change in gear shifting or a slip in the clutch. Does anyone know what this sound may be?
