You'd think so, but every Car I've had if I put it in Neutral on long down hills on the highway MPG goes WAY up. I always do this, if I'm driving a stick.
This car feels like it normally/frequently takes more advantage of down hills, that it feels like it free wheels and stays in 8th normally going down long hills on the highway. Which is great and I think partly why the MPG for this size truck is pretty damn good.
It's just in some instances (not on the highway), have not figured it out yet, it aggressively downshifts.
If it's in "Auto" does "Hill Decent" mode kick in on it's own sometimes?
Or does "Sport" mode also kick in on it's own (When in Auto). In other words, if I start driving aggressively will it downshift more aggressively on it's own when I let off the gas?
It does not feel wrong, it just feels different and a little unexpected.
