My worthless 2 cents: The transmission behaves more like a "track mode" the way I would have shifted on a track holding gears through the turns in my 6-spd porsche and really doesn't belong in this truck. Holding a gear for an eternal 6 seconds at 5500 RPM should not be considered normal. Ideally sport mode would only make the throttle position more progressive and allow higher RPM's "when accelerating only". I don't feel "tow mode" impacts the throttle position curve and so it is not a replacement for a proper "sport mode".

2015 5.0 with 20,000 miles does not do what you're describing.

I have the 2.7 with 3.73 gears. It does the same. Nothing wrong with the truck.

"Sport" mode wasn't designed for "normal" driving.

So let me get this straight. you 2015 and up owners get a sport mode and a tow/haul too? for fun can you run sport and tow/haul at the same time? just curious

^ no, it's one or the other. Sport is like the more aggressive version of our T/H mode on the 14 and before.

As promised to the OP, I tried to replicate this phenomenon, but was unsuccessful.

However I'm only a bit over 1000 miles and I'm still getting acclimated to the whole tranny sport mode and advance trac sport mode functionalities, so my testing could be skewed.

Thanks all. I think it will be resolved with a custom tune.
