I have this list of stored codes. No check engine light runs fine apart from torque converter. Lock up issues in sixth gear. I believe that’s an issue of transmission service and I’m in the process of flushing and doing. Shift actuators.

any insight on these codes would be helpful? my thoughts off the top of my head are spark plugs, coil packs or an O2 sensor

 

Hi. Can you clear them and see if they come back? If you don't have a check engine light, then they aren't active codes. If they are stored, they happened in the past. Maybe you were working on the truck at some point and the codes popped up but never triggered the check engine light because it was a one time thing.

If the truck is running fine and no CEL, I would clear them and see if they come back.
