U0404 = Invalid data from gear shift control module. I think your ESM (electronic shifter module) is going bad.

Have you had any problems with the way your Commander runs ? Why were you getting the codes read ? If you are not having any problems it could have just been a computer glitch and you should hold off doing anything.
