Are there any diagnostic trouble codes set? is the cooling system full?

Customer: replied 1 year ago.
The cooling system is cool, and there is no check engine light. the trans temp was scanned and was 60 deg. hotter than the engine
Expert:  Scott replied 1 year ago.

Not all codes will turn the check engine light on. see if there are any codes set in the engine module and transmission module (if seperate from engine module). Also what color is transmission fluid? does it smell burnt?

Customer: replied 1 year ago.
we just put a new tourque converter in. The fluid was changed. The only transmission code is "trans oil life" and we don't know how to clear it
Expert:  Scott replied 1 year ago.

The transmission fluid life indicator has to be reset with a scan tool unless there is an option to reset it in th edriver information center. Once it is reset to 100% see if the message will clear or comes back.
