Here in El Paso I cross over to Juarez Mexico a lot. I usually spend 1.2 hours in a line on the Bridge of the Americas. My transmission overheats half the time. I was thinking of putting in a transmission cooler. But I was concerned now that its winter wouldn't the transmission take longer to warm up on a very cold winter morning. What about highway driving isn't the transmission going to be too cool. Thanks for all your help.:read:
