You may also want to manually downshift before an uphill grade so you are in more of the power band when climbing. The automatic will not downshift until there is sufficient pressure which may be too late.
This is true. I think those that say they they just let it do what it needs to do probably should do more reading on how a auto trans works.
There is a reason why heavy duty truck automatic/automated transmissions rely on GPS coordinates to downshift because the trans computers are not smart enough to know when it is going up a hill. It only knows pressures, throttle input, and rpm. So it generally downshifts after it is too late and needs to use more engine power to regain momentum especially when in cruise control.
