While pulling off the automatic transmission filter, a part which looks like a top with an O ring fell out. I cannot find where it goes. It is about 3/4" dia. With a shaft of about 1/4" dia X 1" in length.

I found out through an other source that it is a plug that the factory installs after the fluid is added but before the fill tube and dipstick is installed. When these are installed, the plug is pushed by the fill tube and ends up at the bottom of the pan.

So, basically, it is not an issue and can be trashed.
