Transmission cooler options

Thanks for the reply. The transmission thermostat is set for 180. The new radiator I bought from radiator express. It’s a single row, however thicker than stock. The sales rep explained these provide considerably more cooling surface/capacity than oe. Instead of plastic coolers, all aluminum. Looking back I wonder if I should’ve opted for two row? Anyway, it Only gets warm when on freeway at speed. Cools down to 190-200 when in traffic. No fan clutch, has giant variable speed electric fan OE. Which works. I am still using the dexcool…and it was flushed very well, guess new ac delco tstat could be hanging up, won’t rule it out of course…but doubtful. So, yeah, I was not sure whether or not to plausible.
