Lack of Inertia? Are you talking about the inertia in the Torque converter?

Autos have the run away feeling when you are off throttle because when the engine rpm drops the torque converter releases and takes load away from the gearbox. Some Autos are programmed with gradient control logic so they can tell when the vehicle is going down hill and then hold a lower gear with the torque converter "locked up" rather than going straight to the higher gear. Some version of gradient control logic work up-hill too by not allowing the box to shift up thus taking the motor out of the peak torque range.

Sorry if its a bit off topic, just clarifying...
