Help with figuring out part.

Hello. I took apart the transmission on my Astro van and I cant figure out where the two parts came from. Please help. Please see photo. Thank you.

What is the approximate diameter and width of the pieces?

[vanfan]

The diameter is 3" and the thickness of the pieces is about .018" Thank you for your help.

I showed it to someone who has taken apart many of these transmissions ... didn't recognize it.

Could it be from the engine? Thank you.
