I own a 2014 that had a transmission shudder when shifting from second to 3rd gear. CPU flash mostly fixed this.
Now it has developed the same shudder/vibration when applying throttle at 75 + miles per hour. This is relatively new. It goes away and smooths out when I lay off the throttle. Any ideas as to what this could be? It feels like the same shudder/vibration that I felt when shifting from 2nd to 3rd
