The noise I get is far from nasty. I just live with it and most days I don't even hear it. When it's pretty cold out is when I can hear it most. I changed the fluid once so far at 50k miles. I didn't have ISTA running at the time so I couldn't flush the cooler. I plan to change the fluid again soon now that I have ISTA and can cycle all of the fluid out. Already have 22k on the oil change. My SOP for manual trans cars is normally to change the fluid every 50k miles.
