That may be so but the modern dumb driver (I would say that would be 95% of all drivers) would not know how to use a manual shift feature. Even those who do -- like all those boy-racer auto-reviewers -- do not use them. Those auto-reviewers themselves claim that they will try the manual shift feature once or twice and then forget it, just letting the transmission shift for itself.

The "real world" of transmissions? Sulu nailed the real world of transmissions--move outside of the tiny percentage of drivers who are in these forums, and ask them if they have ever shifted their transmission to another forward gear other than "D". See how low that percentage is....I'm telling you, it's really low.

And, it has to be a low percentage. Because it's getting near impossible to find a car with an MT. And if you don't know how to drive and MT, chances are, you don't understand the point of shifting through the gears. And if you don't understand the point of shifting through gears, you certainly aren't going to do it on an AT.

It was a loaded Limited, that did not have the 20" wheels. Yes my Sedona is a completely loaded SX-L.

What I meant by that term (maybe I could have chosen something more clear) was the experience I've had with most traditional, non-CVT automatics. Some of them have been programmed quite well, and readily kick down under part throttle without manual-downshifting. But many others are sluggish, lazy, or appear to have programmed mostly for CAFE numbers.

I agree that any drivers have no conception of when they should manually downshift or upshift an automatic. They just sit there and let the engine lug along at low RPMs in high gear at low speeds. That's fine on a highway if you are actually going fast enough, but can be very hard on the engine if you (or the transmission) are lugging it at 1500 RPM at slow or moderate speeds.

Somehow, we all got off topic with transmission-programming. We were discussing the new Pathfinder.

What can a driver -- especially a modern, dumb driver -- do about that? If the autotrans in a modern car cannot take care of that situation, it is not a modern autotrans. It is so easy to program a modern autotrans to save itself.

I just had a '16 Pathfinder for a rental.

It was a lower trim level, and it was remarkably cheap inside. Lots and lots of hard plastics everywhere. Hopefully some of that was addressed with the '17 update. I was expecting it to be more on par with my sister's new Murano, which has really impressed me with its materials, fit, and finish.

On the plus side, the ride was pretty compliant, the CVT was much less annoying than I had expected, and it was very roomy, with the exception of the cargo space behind the third row, which couldn't even fit a small/medium sized cooler.

I feel like Nissan does a nice job on the styling and fit/finish on their "premium" cars like the Patrol, Maxima, Murano, and Infiniti line. Its just their mainstream cars are flat out ugly and very cheaply finished(Altima, Sentra, Rogue, Pathfinder, Frontier, etc). Its kind of crazy how wide the quality gap is with Nissan between their cheap and expensive cars.

The QX60 never had great materials either. I haven't seen a 17 Pathfinder, but I have seen a 17 QX60 refresh and the materials are better, theres a sitched leather dash, etc.

One other annoyance I forgot to mention was that the liftgate doesn't lift high enough. I'm only 5'10" and couldn't stand up under it without hitting my head. Very frustrating.

I'm going to be a bit sexist here and say the Pathfinder is not a man's car. Its designed for the wife with kids, as in if the liftgate were higher your short wife would struggle to get it closed.

I believe it only is adjustable on the powered hatch. Our rental was manual.

(I could be wrong, but if there was an adjustment, I couldn't find it)

Makes sense. My experience is with the QX60...
