AT codes don't necessarily cause SES/CEL and most OBD2 code readers don't read EGS codes. The only way for engine speed to change with vehicle at a constant road speed is if AT is changing gears, slipping or torque converter is going an & out of lockup. If you manually put trans in 3/4/5 gear does problem disappear? Trans or trans sensor issue sounds believable.
