You can read it here: 30362399Flat Tow 2017 GMC Sierra 2x4I have a 2017 GMC Sierra 2x4 that I want to flat tow. In the past, I had a transmission cooling kit installed on Impala so as not to damage the transmission. I would stop and start the car every 200 miles or so. I can't find anything online about doing this to the Sierra. Has anyone installed a transmission cooling kit on Sierra to allow flat towing of a 2x4 vehicle?
