Resurected again, I had this happen the other night when I nailed 2nd gear WOT the shifted. No codes were present. Restart and it was fine. I wonder if it was an over boost that my fuel cut defender blocked?

You can have temporary DTCs (trouble codes) and memorized DTCs.
AFAIK if it is a temporary one, just the cruise control light will flash, /if/when it becomes a memorized one, both the CEl and cruise control light will flash.
If you want to see what it is use LV (Learning View............. search if you don't know what that is) and check the ECU when the car is still running, don't turn it off, as you will likely lose the code.
