I have a 2014 R/T M6, like most, I have problems with the 1-2 shift being notchy to downright difficult. I have the skip shift turned off in the tune and installed the standard Barton shifter. It helped and was substantially more robust. I then angled the shifter handle more towards me, and again more improvement, but still notchy. 2 weeks ago I orderd a replacement shifter ball knob from Barton. I went with the weighted one. This thing is solid billet and weighs 1 pound by itself. I've read that weighted knobs improve shift feel. All I can say is that this single purchase has made the most difference of all of the above. Super smooth and easy shifts in all gears. The CDV delete is coming next but the weighted knob by itself did wonders. If you have an extra 80.00 laying around, it's worth the investment. Hope someone else benefits from this mod. At the least, it has many personalization options and feels much better than the plastic knob.
