whistle type noise.

The other day we had a huge rain storm, well anyway i went threw a huge puddle.
Now the rain is done and over and since then my clutch when im going threw the gears after i push it in makes a whistle type noise, or something letting pressure off or something.
the clutch isn't slipping at all, still works in all perfect order. this was about a week ago and i figured water just got in something and would dry up. well after a week of 90 degree heat i have figured it isn't going to dry if it hasn't yet.
i really have no idea what it is and its getting kind of annoying.
