Is your trans cooler inside the engine or inside the radiator? I've only seen trans coolers in the radiator, never in the engine. Have you ever looked at the temperature in the radiator, in the tank AFTER it's been cooled? It is NOWHERE near 185°F. In cold ambients the water temperature near the trans cooler is outside temperature, plus or minus about 5 degrees. So in 0°F outside temps the cold side of the radiator will stay at about 0-5°F near the trans cooler. How well will that heat the transmission?
Never means never. It doesn't mean when it's convenient.
