My battery light came on throughout the week. Then my car would only shift in second gear and reverse then broke down won't start. Codes are p0700 and p0622. Battery and alternator are fine.

Hello,

This code is for the TCM and the alternator which if the alternator is bad it can cause the TCM to malfunction. Let test the alternator first to see if it is throwing AC voltage and to check the output.
