Oil change reveled absence of part under transmission

[JCG]

Good afternoon,

I would appreciate any advice on what this piece is, in attached to post, and how I may obtain this part.

While changing my oil, I noticed the open space under transmission. Looked inside and this piece of rubber was jammed up inside. I do not know what it is or how to obtain this piece. I have conducted a fairly extensive search online although I would not know how to describe, looks useless but I am sure it is not.

thanks in advance

Justin

That's the inspection cover for the flywheel . It should be an oval rubber plug .
