My thoughts:
Excessive windage in the rotating parts, which could aerate the fluid. The normal fill is about the bottom of the valve body, so it doesn't take much higher to reach the rotating parts. And aerated fluid could be bad news.

One quart of over fill can kill most automatic trans in less tha a 100 mile trip at 60+ MPH way better to be one pint low than one cup overfilled
