Not a good sign; more like bronze not brass. Only a couple of places that metal could come from; cam plate pinion bushing, either end of the connecting rods or the crank thrust spacers.
Rocker arm and wrist pin bushings also but you hear them long before they ground enough to seen in an oil change.

Which is why I didn't include rocker arm bushings in the list; less than 1000 miles, doubtful that rocker arm bushings would be the source of the copper, brass, bronze or pixie dust that the OP is seeing. Now, the OP is referring to trans fluid so I have no idea where the sparkly stuff is coming from.
The brass flakes maybe are plating on the shift forks. Until it levels off even, you will see it. Just my opinion unless you see big hunks and I seriously doubt that is even a concern. Did you use the service manual for the plugs. The transmission should pour out just like the engine and primary. That oil pan on the bottom of the transmission with a plug that looks like the transmission and a plug and one that is the oil pan and one on the engine that is not the engine is confusing.

I had the same issue on my 08 ultra , drained all 3 in same pan , and found some brass. Took the oil and brass back to dealer so they can note it on my warranty , I now have 52,000 miles and no issues!

good stuff but you really mean shift forks.. not dogs.

Makes sense. Is the shift fork plating something unique to later models? Why plated when it is destined to wear off?

Thank you

This is off an 06 Softail. Not sure about now or other models. I doubt it's designed to flake. It's almost like a sprayed on coating..I just figured it was the high points. However, it also could have been some type of additive Harley put in when assembleing the transmission like someone mentioned. One reason why someone should not put GL5 lubricants into a Harley transmission. However, just my opinion.
