Hey guys its been awhile since ive posted but i just got done changing the transmission filter an oil in my truck< when i pulled the pan there were to pieces on a snap ring laying in the bottom of the pan stuck to the magnet when you put them back together the way they should be its about 5 inches tip to tip so im guessing its about half of the snap ring. My question is where is it from? i didnt see anything out of the ordinary truck shifts fine. Last time the pan was off was 4/11/10 at 91,000. its is now at 108500 miles its an 04 2500 any help as to where these pieces go and how much time ive got till its gives up would be helpful thanks again guys

Pretty sure it is from the O/D unit and you shouldn't wait to have it taken care of. This has come up more than once over the years, and a search might find the threads, I would search something like metal in pan, snap ring in pan.......
