A couple thoughts.
Post the actual codes.
These have been known to have egr and coolant temperature sensor problems the latter may have to do with the high rpms, especially since it seems temp related.
Should change the trans filter every 30-35,000 if it were mine. That one is brutally simple, just a spin on. Should drain out the as well and add fresh.
