I drive a 2004 sti that is approaching 15000 miles. Ive read a couple different opinions on the 15000 mile service and am wondering if theres any fluid changes i should do besides the oil and tires rotating. Is it good to change the tranny fluid this early in the cars life? or should i wait for 30 k.. I figure i need to top off my fluids at least if not changing some of them. My second gear has been feeling a little rough and i was hoping a fluids change would do the car well. Any ideas for what exactly i should do?
