    What model# is that? Looks odd. Possibly a return up top?

    I honestly don't know. Any other pipe plugs in it? Up top? Does it have the HALO?

    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.

    Where do you run? You can get by without it. I wouldn't personally. You'll get oil temps up around 250* summertime.

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