A transmission cooler inside the radiator dumps the heat into the coolant.

A transmission cooler in front of the radiator blocks some air flow and adds heat to the air that does flow through it to then pass through the radiator.

While either of those do not completely stop engine cooling by the radiator they make it harder.

Certainly the tranny heat exchanger in the radiator marginally adds to the heat load. But I still don't think this is the issue here. How much hot liquid is going to flow through a 3/8" tube?
Thousands of vehicles are running around with radiators successfully cooling with these tranny heat exchangers in them.

I have been doing all of the same things you have for the last year. I think i have mine beat and I think you are close. What i didn't know was how to properly burp the air from the system. Broncobowsher posted the filler neck for the high upper hose and that's what fixed me. Here is a link to a bad video i made burping. I removed air bubbles for over 30 minutes and then never had the cooling issue again. I ended up with a mechanical fan and a 195 stat, just dialing in the depth now.
