Thats because the gearbox is adaptive to the drivers style of driving
I wish my gearbox would adapt to my style of driving it changes up a lot later than when I would change up the engine never seams to have any work to do I think that the mpg would be much better than it is.

For long uphill hauls in France (done them so I know how long they can be) You need to keep the engine at peak torque as much as possible. This is the most efficient engine speed, and the engine will produce less heat and use less fuel relatively, as a result.
Peak torque is about 1950 rpm I seem to recall. So I used command shift on both my old 2.7 and my newer 8 speed 3.0 to keep the revs in this area.
No issues encountered even on a hot day. If the car can’t maintain the revs, because the hill is too steep, you need to drop a gear and possibly slow down to maintain peak torque. Not always ideal I know!
