Metal shavings on trany plug

[GTABurnout]

Is this a problem. There wern't much but still there was some. Is this just normal were or should the tranny flushed and checked out. Still shifts fine.

Normal to have a slight powdery residue and small shavings over time. Just change the fluid frequently. I used to change it every 5000 in my last auto T/A before I converted to a manual....
