Hopefully, that may provide guidance to others that have the rough shifting return. I am expecting this condition to last.
What's up guys! Just wanted to chime in here for others who are having this same problem. I just bought a 2014 Jeep Grand Cherokee Limited 3.6L a week ago. Its been having the same 1st to 2nd, 2nd to 3rd, and downshift gear change problems as everybody else here.
I pulled the fuse (F60) for 20 mins to see if that helped like others have been doing, but it didn't seem to help at all. I took it to the dealer yesterday (the 2nd day I drove it) to see what they said.
Low and behold, the tech calls me an hour after saying that the Valve body ShewString above got in his GC was bad and they would be replacing it as well as updating the ECU and settings to the current version.
I was very glad they diagnosed and acknowledged this as the problem during my first visit, and best part it is all covered under warranty!
Thanks again Jeep Garage, I'll post later in a few days with an update to how she drives when I get her back.
