What did your car shoot the code down? It is dangerrous to steal your shifting. Don't change your transmission yet. Reset itself is a big problem for diagnostic.

"very dangerous on highway"---depending on priorities--like LIFE---maybe getting it to a local shop(get references) and having it driven and diagnosed first hand might be a good idea.
