Thanks for the replies! I felt around inside the hole, and kind of scrapped what I could out/off the magnet.
Here is a picture of the bottom of the transmission drain bucket, should I be concerned about this amount of metal particles? Anything I can do about it? None of them are very big, maybe like the size of small-medium sand (I know it's a scientific unit of measurement

)
EDIT: Tested with a magnet, quite a bit stuck, but all very small particles.
I also cut/tore open my paper oil filter. Very glad I'm upgrading to the LN adapter, it had a few bits of metal in it as well. Some of them maybe half the size of a pinhead.
EDIT: Tested with a magnet, nothing on the paper filter was magnetic, except for maybe a dozen or so very small sand sized particles. Not sure what those bigger particles could be. Sending a sample to Blackstone.
