Not sure where the plug went and it doesn’t seem to leak anything but I need to plug it up…

Looks like the torque converter is visible through that hole if that is the transmission.

Is there supposed to be some kind of plug there?

Looks like a hole to access the bolts for flex plate to torque converter.

If it was mine, I'd look for a pipe plug to fill the hole - just to prevent the odd chance for road debris to enter (which is highly unlikely given the hole faces the rear of the coach)

Thanks Kyleb, I’ve got to measure the hole but my micrometer is at home - will check it tomorrow when I get back and find a plug.
