If you don't mind spending 125-ish, I'd get a tru cool LPD49211. It's a 6x23x3/4 and fits in the front of the condenser like a glove. Its getting cooled by the mechanical fan and also by the elecric one when its started. It's rated 30k gvw. You can also take the electric fan control and move it to a button and install an oil temp gauge so when you see high trans temps, you can start cooling it manually. If you live in a cold environment, you can also get a thermal bypass valve (I live in Cleveland oh so I need it).bypass valve is another 35-ish bucks. I got both radiator and valve brand new from eBay, but I'm sure you can find better prices if you have time to search. Personally, I am for removing/delete the factory in-radiator transmission cooler since IMO it does more bad than good in warm/hot climates. With the bypass valve, you don't need to warm up the oil, few miles on 10-20 F and its over 100. My 2 cents...
