This is caused by the heavy solenoids damaging the bores, There is a MUST HAVE Tool for resizing those bores:

Agree Phil, those valves can cause nightmares if they are draggy.

We tried using Ratiotek kits along with a couple of Sonnax valves (not pr valve due to incompatibility with Ratiotek) and found the transmissions took a very long time to adapt, and had intermittent harsh shifts/engagements.  We switched to the Sonnax Zip Kit with the last 3-4 10R80s and couldn't believe how quickly they adapted and worked very well.  Just make sure that those control valves fall in/out of their bores with their own weight.  They seem very susceptible to sticking with no return springs.

 What are most of you doing on the 10r80 valvebody wise ?  still using new Ford valvebodies?  or using the zip kits on them ?  I've noticed the price has creeped up on them from Ford , I just finished one and the valvebody was right at $700,   imagine it will continue to increase as time goes on
