PO700 is a tranny code
i may be wrong but i believe you have two different issues. one is with the tranny not shifting correctly and the other is that you may have a boost leak or something of sorts not letting your car run correctly at idle, and thats why your getting a misfire. there could be a lot of things but id check for a boost leak first since there usually easy to detect for the most part.
i am not familiar what a automatic would do if its having issues maybe its causing all of these problems, just throwing out things that may help.
i am looking into the tranny code but it could be a number of things.
but looks like you will have to tow the car home, best of luck to you i will post back if i find any information that may help you in any way.
