Can an AC Installed make the engine run hotter than before?

[motorcritter]

Adding an auxiliary trans cooler is cheap insurance- pulling trailers, running a high-horsepower engine and extreme road conditions (mountains) all are tough on automatic transmissions. When I ran a transmission shop, on FL, coolers went on nearly every overhauled unit. We didn't have many come-backs or warranty work because of it. A transmission can run too cool, so a thermostat is a good idea if you're in one the areas where winter temperatures get below freezing on a regular basis.
