Better question. Do you want to risk cooking it with how hot things have been?

Ha no but I got a no questions ask warranty on it. I'm gonna take that black cover off and see what's under it.

Pretty sure the cooler line ports “In and out” are under the 5 bolt plate/cover. The cover allows oil flow thru the trans when a cooler is not installed.

The pipe plug bottom left of out is just open to the case and is common to see trans temp sensor.

This is 100% the correct answer. You need to remove the block off plate in order to plumb in an external cooler.

Take the five bolts out and remove the cover. You will find two threaded holes for the cooler lines under it.
