So I just did the first ATF dump and fill on my 2017 Accord Touring V6/6AT, at just under 52k miles. The fluid was definitely dark, but not burnt smelling and still had a reddish tint. The concerning part is the amount of brass-colored specs in the bottom of my drain pan. Does anyone know if this would be considered normal wear, or possibly from initial break-in? There was a little bit of metallic particulate on the drain plug magnet, but not too much, IMO. I've noticed that the trans downshifts from 2-1 and from 3-2 a bit harsh at times but it's always done that since new. I had the car at the dealer for what I know now to be VCM operation noises, and also a rattle while under light throttle application. No parts were replaced and the tech found nothing out of spec. They even sent a torque converter snapshot to Honda to determine if a judder TSB was applicable on my car. It was not. I plan to do another dump and fill this weekend when I do an engine oil and filter change. Hopefully it's nothing worrying!
