I am assuming [ and I know what that means ] that its under warentee .
Changing the fluid should be part of that , but you never know what they think .
Just looked at your millage , maybe not covered , if not , then you should never go to the dealer again , unless you've got one of the few good ones , but still , if you have or can find a performance shop in your area , thats where I'ld go .
Might be a good additions to are sources here , fourms , a search by location for performance shops & ratings .
You might start at the top on the page under site features , then links .
