Hello and welcome to JustAnswer!

It sounds as if the trans is in limp in. When the controller sees an issue that will prevent proper operation it will set a fault code and lock you in a single gear. If the trans itself has truly been ruled out then you most likely have a wiring issue.

The first step in diagnosing the problem was to use a scan tool to see what fault codes are setting and then testing can be done from there. do you know what codes are setting?
