I have a 2005 GC SXT. It's rated for a towing capacity of 3,800 lbs. I'm planning a summer vacation which involves towing my 3,000 lb. boat on a 12-hour drive.
A friend suggested that it might be worthwhile to have a transmission cooler added. Today, I went to my dealer for an oil change. I asked for an estimate to add a tranny cooler. The dealer said that there's no tranny cooler listed for that vehicle. He didn't think that there would be room to add one. I haven't looked for myself, but I noticed that the factory "trailer tow prep group" option, which I didn't get, supposedly includes a tranny cooler.
My two questions are: Does anyone know if a transmission cooler is actually available (My dealer has been wrong before.)? Would a cooler be a good idea for the trip that I'm planning?
Thanks
