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.

Thanks for the information. I thought it might have something to do with wanting to up-shift or the the TCM saves itself from destruction by not allowing the downshift at too high of speed.
It makes me wonder what else is wrong in the tune...
