I just leased a 2014 ford fusion about a week ago, so I am still getting used to it. I finally got the sync system down (for the most part) but the thumb shifter confuses me a little. I was wondering if there was anyway to keep the automatic transmission from upshifting to run the rpms a little higher for faster acceleration? It seems as if the car usually jumps up a gear before I even get to use the shifter.
