I was just thinking about that, looking on the net for a photo and wondering if the op would take a picture of the side of the transmission where the hole is but not so up close like the last photo. There's something screwy here I think.

Here is a pic of the trans and of the service manual. The park-lock cable is ahead of this hole on the underside of the trans in this pic.
