Yes..I don't manually downshift going up hill. My transmission is a 6 speed and has the newfangled semi-auto thing where I could increment or decrement the selected gear. But I find it easier to just let the transmission do it's thing. If it pops up into a higher gear going uphill, which it often does, I let off on gas for an moment until it drops back, and gently ease the pressure back on.
My van gets the best mileage at 2000rpm, so I strive to stay in that range.
I've yet to need downshifting on the way down. But I'm pretty used to having crappy brakes. So by habit I'm always trying to avoid braking going down hill.
It is interesting how Barometic Pressure, Altitude/Air density,Temperature & humidity creates a Large array of conditions that make the variable MPG on the "Rig".
