Afaik, its because there isn't the same capacity for overrun that the 4speeds had, due to the design of the internals. The 6l80e's are clutch-to-clutch, and setting too high of a downshift speed would cause more slip between clutches then allowed, and it would probably want to try and shift right back up.

Thats how I understand it from the reading. 6l80e's confuse the crap out of my because the Truck,car,and 'vette's were all setup and programmed a little differently.
