2013 C6 with A6 tranny. Been running great but recently after highway driving, stopped at redlight and car would barely move forward. Seemed to be lugging. I pulled over, Put in neutral, shut it down, restarted and it took off like a bullet. Has not done it since then, but it felt like it was in a high gear. Any thoughts??
C5 Diag, excuse my lack of expertise on OBD2.. Maybe my scan tool is not the best, but i'm not sure where to go to find the data you mentioned. My scanner is AUTOPHIX 126P https://www.autophix.com/product/om126p
In the manual, under DTC example, under "subsystems", it mentions transmission controls. I am not sure what look for here.

NO !!…that’s OK !!…I looked and you basically have a “code reader”…a factory level scan tool is what’s needed to be able to view those modules I mentioned…in each module you can view many data PIDS to help with a diagnosis….usually these code readers can only view “P” or Powertrain codes…can you view “C” and “B” codes and look at this live data ??…most owners of these code readers only use them to look at and erase codes…a friend of mine owns an AAMCO transmission shop…I’ll try to bounce this off him…I don’t do a lot of transmission work.
Tranny not downshifting??
