It does not run rough when idling and it is not hard to start when cold.
The towing button on the side when you press it in does not work and it did before. It would gear down going downhill just by lightly putting on the brakes and it would automaticaly gear for the hills too. That doesn't work and there is no power going uphill
The code for what? We just found out the the truck is a rebuild and it has a 2006 6 L engine.
