I have a 08 C6/A6 and I was adjusting my trans tune for the track, and when I load my new tune the car will drive about 100yds before throwing a check engine light for a stuck #5 pressure solenoid. The part that confuses me is if I load my old trans tune the car drives fine but misses the shift. The only things I changed were the WOT shift mph and the speedo Calc. Any help would be great.
Trans tune 1 works
Trans tune 2 does not
Thanks
