Hello, I’m new to the site and I’m having trouble figuring out a certain spot on my 04 v6. I have a picture that I will attach, but there is this hole that is past my oil pan, and it looked like it was plugged with some kind of plastic or rubber, but I have no idea what it is and how to find a replacement. Any suggestions? Thanks in advance! (Notice the drain plug, and then the 2 inch diameter hole, that’s what I’m talking about)

 

The hole is in your transmission , it is there to get your torque convertor nuts out . Rubber plug fell out , it is in the case maybe ?
