Yes. Kinda gives you an idea of what the truck can do. Not to many of us going to put our vehicles thru what these guys do. Its kinda fun to check a few of these out on a rainy day, they test out most of the pick ups. Hey thanks for the tip on the web address.

Come to think of it my '08 Buick Enclave with 6-speed trans used to dive into the highest gear and it was very annoying. I didn't tow with this vehicle. In reading recently about the 8-speed trans made by ZF and used by many including FCA with reports of software making shifting a problem I would look into that.

Our 2013 pathfinder does around 3000+ rpm going up steep grades. I think it's normal. The newer engines are designed to run at higher rpms. The ford eco-boost is a 2.7 liter engine must run at a higher speed to get its horsepower and torque.
Just take it slow don't. 18 wheelers go slow up steep grades and while getting on the highways everyday.

It will even downshift to 2nd on occasion of the grade is really steep and our speed isn't too high... this takes the RPMs up to around 3500. To us this seems like normal behavior for modern engines, and I though (but I could be wrong) that this gives us the torque we need.
I agree - that all sounds appropriate and normal. 3500 rpm is below but close to the peak engine torque speed of 4000 rpm (which is a good range for efficient power production) and still well below the speed for peak power production (5600 rpm). As long as you're getting as much power as you need, it's all working well.

If you are going up the grade as fast as you choose, you're getting the torque that you need to the wheels.

Yes, engine speed for peak power is higher than it was long ago, and higher than it is for much larger engines. The EcoBoost engines, on the other hand, are turbocharged so they don't need to spin faster to make more power than a non-turbo engine of the same size.

I think the shift problems are (or perhaps have been, since they may have been resolved in the Cherokee) with the 9-speed (9HP) rather than the 8-speed (8HP)... both of which are ZF designs (although FCA makes the 8HP themselves).

Suck it up Escapist.
Just had the vehicle into the dealer, the engine and transmission checked out with no faults. Can't afford or want to spend any more. I will have to remember to drive manually on grades, shift into and out of 3rd range in the mountains. I have always driven at or below the posted speed limits, especially when towing. Idea!! Lottery ticket, buy a diesel Titan?

Don't feel bad- I took my Yukon in when I was noticing delayed upshifts in CO last year. Only cost me $105 to learn all was OK and by the way here is a Service Bulletin on when and how to best use Tow Mode. Actually had some great info on the whole system including engine grade braking.

So now you know- and it goes back to Reace's advice that at first sounded like a dodge to me but makes complete sense: When asked what he recommends for a tow vehicle the stock answer by he and Dennis is "That depends on what your expectations are". You can use a V-6 but have to adapt to managing RPMs and tolerating the sound associated with achieving needed torque when climbing.

Not sure what they are thinking, but Nissan is running ads in Vancouver market for a new model sedan.
They show it alongside a travel trailer that appears to prevent it from passing on the right, which it continues to do, by racing through a construction zone and eventually overtaking the RV.
Oh, and it has a stupid name.
