I have the same issues with mine. I have a 2009 RAM 1500, it is a two-wheel drive regular cab. Everything is stock on mine. I have 17 inch tires and a four-speed automatic transmission. I was reading this thread to see if there was an actual fix…I suppose the only thing to do is live with it or change the gearing.
I'm not sure if the v6's use the same trans as the v8's but if they do you have a 6 speed trans.
