Its called a dust plug i believe. Found it the first time I dropped trans pan. Was for keeping dirt out of pan during assembly.serves no purpose now.

So that means the tranny was never opened? The screws holding the pan are a 10mm socket, aren't they supposed to be 1/2 inch?

Not sure the year your working on.can't see it on phone. But mine are 10mm if I recall correctly
Worried the hell out of me until I figured out what it was.

When assembled at the factory, that is the plug that is used in the dipstick hole. They just push it into the trans when putting in the dipstick. Yes, that means the trans has never been opened. Again, you are right. Unfortunately, Ford and everyone else went to the stupid Metric system starting in 1974.

That would explain the huge METRIC label on the bottom of the oil pan.

Now I purchased this tranny from a guy who had it sitting for 10 years and hope its not fried as the oil was dark brownish in color and not very clear.
