Only 5 passenger suv capable of towing over 5000 lbs. Recently purchased a 2014 Grand Cherokee Laredo 4X2. After 70 miles transmission started banging into gear on downshift. Took it back to the dealer, MIL multiple codes, they determined the trans could not be fixed and Chrysler is sending a new one. Satisfied with dealer response, love the vehicle, don't love the problem. Has anyone else experienced a similar problem? Any thoughts on why this could have happened. According to what I have read the trans is used in both 4X4 and 4X2. Have not read any bad reports on the 8 speed trans, it is used in many high end vehicles.
