It has been a little over 3,000 miles since my last oil chnage, and I had it changed today. But that got me thinking, it has also been a while since my last tranny fluid change, about 9,000 miles. I checked the tranny fluid, and the color is like brown/reddish/orange. Should I change the fluid soon? I was planning to change it at my next oil change, but I am not sure. I dont have the prelude car manual, so I'm not sure what HONDA recommends. Your advice?
