actually Ion the stuff on your drain plug in the engine is normal also each oil change you do you will always have metal shavings on the end of the tip of the plug and if you don't then you have an issue its got something to do with keeping the engine clean and thats why missing oil changes isn't good as so much of it builds up and because really bad.
but yes the stuff you see if your tranny is normal so your good to go just remb to replace your tranny filter too
