Hi I am new on the site. I recently purchased a 2011 Ram Sport. I traded in a 06 silverado. I don't know if it is just me or if there is something wrong but I feel like the truck doesn't want to shift down when I give it gas. It will vibrate at 45 mph and 65 mph when I give it gas to speed up. I have heard that it is just the way the motor reacts because it is trying to conserve fuel economy. Any advise or input would be great. Happy to have found a site with some much interaction!
Neither the bogging nor the vibrations are normal operation. There is a PCM flash that will improve the shifting, so check with a dealer and see if it's been done to your truck. They should perform this at no charge as long as the warranty is valid.
