Maybe someone can help me out here. I have a 2013 Dodge Ram 1500 4x4 w/ 5.7. Was sitting at a light and my ERS engages and is now stuck perpetually in 4th gear and my Check Engine Light is ON. I cannot even toggle to other gears. I've tried putting it in park and shutting it off and restarting but the problem remains, goes right to 4th gear. Any ideas out there?
