My second career is at a community college. I asked one of the automotive instructors about adding the extra cooler to supplement the GM extra cooler. He said it wouldn't hurt a thing. Mine is a 2000 model. The older vehicles do not have the transmission oil thermostats like the newer vehicles. So, he said that for my 2000 it wouldn't hurt at all. The older vehicles do not need the transmission fluid to be at a certain temperature range like the new vehicles. In a new(er) truck it might be an issue because they are designed to run within a temperature range. He said that when towing it's going to get warm/hot anyway and in winter it will still warm up. But, it doesn't have real specific temperatures that it needs to operate like the late models. So, I'm adding the extra cooler to the Suburban.
