I just purchased a 2016 2ss yesterday and today the cel came on and the transmission started not wanting to shift and the D was flashing on the cluster. The codes are

P0700 just a generic tranny code
P0658 this says Actuator Supply Voltage – Circuit Low

I know they are both to do with the transmission. If I clear the codes it drives normal until I park it, but then they come back. Do I need to reflash the pcm and tcm or does the harness need replacing. I searched on here but I couldn’t find any clear answers.those where the only two possible solutions I could find.

I told my wife I could teacher her to drive a 6spd, but she had to have an a8.
