    Hey guys. I’m usually over on the idi part but I’m having an issue with my dodge. One day we had driven through the snow so we locked it into 4x4. Ever since that one time we went into 4x4 it hasn’t shifted into overdrive. It’s the automatic trans by the way. The speedometer is fine, coolant sensor is fine, tps is fine. I’m not quite sure what else it could be. I would love to do over 55 so any help would be sick.
