Whatever it is, I agree that the 8 speed sounds like a big improvement over the 5 and personally not something I'm worried about.
Mrmitsou: I drove the 2014 JGC just to get an idea about the transmission, since it's going in the 2014 Durango. The JGC also has a sport mode, in addition to the regular Drive mode and the Eco mode. The sport mode is engaged on the shifter, which the Durango won't have, and the Eco mode is turned off and on on the dash.
It seemed to me like you nave the normal Drive mode shifting in the middle, kinda like goldielocks and the three bears, whereas the sport mode changes gears at higher RPM, while Eco shifts at lower rpm. In sport it also seems to downshift at a higher RPM too, like you were engine braking coming to a stop. That was kinda weird, but stopped as soon as I got it out of sport mode (that may be what folks are complaining about, don't know). Likewise Eco would take some getting used to as the computer want to get it in a higher gear at a lower RPM as soon as possible to save fuel. Obviously you don't have a lot of torque at lower RPM. So again D seemed about right.
Rather than use Sport mode, I'd just use the paddle shifters, if I wanted to have a bit of fun, and that's what you'll have to do with the Durango, because there is no sport mode, at least that's as I understand it. As soon as you tap the paddle shifter, the instrument cluster changes from D to show the gear you're in, so it's easy to see what you're doing.
