If you haven't changed the transmission fluid this one's on you. If you have changed it then this will depend on when your car was first put into service. After 3/15/2011 and it's covered under the power train warranty. As for your electrical gremlins those are very likely caused by the Negative battery cable, which GM has directed dealerships to change whenever owners report strange radio and dash problems.
