Well I have about 300 miles on my 2014 Overland and I can say they have made a lot of improvements. The overall feel seems tighter and the feel of alot of the switchgear seems to of higher quality. At first I really didn't like the new gearshift but once I got the feel of it now I like it. The Hemi is great lots of power much better than the pentastar just the sound alone makes the hemi worth it. The 8 speed trans is smooth and just runs through a series of quick short shifts up to 8. The only negative I could say about the 8 speed if anything is when slowing down I feel if shift sometimes at lower speeds and seem to have some engine braking at lower speeds 20 to 30 mph but not bad. It seems they have tuned the air suspension in a little more and I also have noticed I don't hear that quick air noise from the tank I used to hear. One other thing I have noticed is the trans temp on this 8 speed runs around 190 to 200 after its fully warmed up 10 miles or so I think that is hotter than my previous one. I'm sure its normal but I might post a thread on that to see what others are seeing. Overall I am very happy with it.
