It looks about the same as my 2016.

It's right under the aluminum thermostat housing on top of the transmission. It's a bit hard to see. You'll probably need a flashlight.

the vent plug is not a plug- its a vent cover- it has a tiny hole in it - because it needs to vent.
its not the fill plug.

Is that little black thing in the picture above the vent?
