To be honest its well documented in the forums that almost all 2015 Chryslers on all models experience a soft shift to a hard shift from 4th to 5th gear and also from 2nd to 3rd gear. It is normal and I'm sorry to say but you'll have to maybe live with it. My 200c does the exact same thing. Granted its a soft to mild shift nothing hard but I always know when its on 3rd or 5th gear.
