The only thing I can think of is, with the performance setting, that when you are at WOT, the shift solenoids are getting flooded. Meaning that they are getting to much fluid pressure on them and they can control fluid direction, so it goes nuetral until you let up or it can block the fluid.

i had the same prolem with my 04 ado....ended up being the 3rd gear solenoid...after that it was fine
