fine brass particals in trany oil

[Dragbear]

I have been sled pulling with my 2009 Chevy duramax and I check the oil after each day of pulling. I find some fine brass particals each time I check it. Is that normal under extream conditions. I make around 700 HP and pull with a 3rd gear start on my Allison 6 speed.

Not normal.
The only place brass will come from is the washer on the C2 clutch hub or planetary pinion washers.
