You maybe reading into it too much. Why would you want to disconnect the roof controllers? There is no reason for CVT to be at fault here. There has to be a good reason for pedal sensor to go bad and I don't see it. The more you mess around with things that logically seem to be unrelated, the more issues you will create. So think simple first.
Clearly, the ECM and TCM are getting data that is either in error and gets interrupted. As the result your MO is placed on limp mode because computer wants to protect the components. It seems to me the issues you are experiencing has to do with or around the alternator replacement or things that you touched during that process. Even though your battery is new, I would disconnect it for 15 minutes and re-install it. Then carefully check the output of your new alternator, both amps and volts to make sure nothing is off. Then check around and disconnect and reconnect any connectors that you have touched. You maybe pleasantly surprised.
