No power in 5th gear when towing a small raft..

I tow a 14ft raft on a small 12ft flat bed trailer. The last couple weekends while driving up hill in the mountains (Colorado 8,000-10,000 ft), I noticed something odd and troubling. While going up hill in my 2014 V6 overland I noticed that I was over 5,000-5,500 rpm in 4th gear and the car would not shift to 5th. It would also not increase over 5,500 rpm no matter how hard I mash the pedal. Then if I manually shifted to 5th, I would sit at 3,000 rpm with my foot on the floor and the rpm would not increase. The car would just sit there in 5th at 3,000 rpm with no increase in power.

Has anyone dealt with this or have any idea what is going on? Is it simply the V6?

Thanks!

I'm guessing no one has experienced this?

Sounds like lack of forced induction at elevation

Plus a lack of information.
Which mountain? What kind of grade? What roads?

How heavy is the trailer/raft, and what else might be loading the vehicle down.

I've seem some rather heavily laden V6's scoot up I-70 right along with normal traffic. Don't know if they have engaged sport mode for more oomph and higher shift rpm or not. They don't appear to be overly taxed by the altitude even on Loveland at nearly 12K.

There are other paved 2 lanes that are much steeper.

Re: No power in 5th gear when towing a small raft..

More info request granted!

On I-70 headed West from Denver. Happens the most on the steep grade on the way up from Georgetown. The entire load (boat+trailer) can't weight more than 1,000 pounds, and I think that is an overestimate.

I do have a K&N "CAI" installed on the car. Not sure if that could mess with it?

It worrysome that I can put the pedal on the floor in 5th gear, and the rpms do not move. When I say there is no extra power there, I mean there is zero extra power, nada, zip, zilch.
