I am certain our 2015 Grand Cherokee Summit has a neutral switch for disengaging the transmission. However we do not tow it. We tow our 2014 Jeep Cherokee Trailhawk (DH daily driver) I do recognize the switch though, since I am usually the one who puts the Trailhawk into 'tow mode' when we hook and unhook.
