Transmission Cooler Recommendation for 2011 Scion xB  

I have been towing a pop up camper with my 2011 Scion xB. I installed a curt trailer hitch, performance anti sway bar, Trd shocks, struts and springs and airlift 1000 air bags in back springs. When not towing I use an ir thermometer on the trans pan and it measures 180 to 190 f. When I towed recently an 1100 lb pop up camper for two hours carefully it measured 200 - 205 on the pan. I towed not in overdrive. I recently tried towing in overdrive being careful to not shift around much and after 20 mins it measured 190 f on the pan. Should I get a transmission cooler? I read that stacked plates are the best. Can you recommend one? Is this a diy job? I installed my brakes and my shocks, struts and springs by myself. Should I install a temp gauge ? Should I install anything else? Should I install a thermostat? Or do they come with their own thermostat? Or is it unnecessary with the u241e transmission? I have done 3 drain and fills on the trans in a row. I use synthetic oil. I plan on doing a trans drain and fill with every oil change. I read that you couldnt recommend the xb as a tow vehicle. I have decided that it makes a decent tow vehicle with the modifications that I have made so far. The biggest limitation in my opinion was the soft springs and shocks and the lack of an anti sway bar. The airbags are wonderful. I am on the fence with the trans cooler. I see a lower temp while towing in overdrive while being careful to not downshift. I was told to never drive in overdrive- I am not sure about that. If you strongly feel I should have a trans cooler- can you recommend one? Thanks
