Just went out to check the shift pattern and this is what it is....
l-2-3-N-R-P=6 (just like Boyd says)
Lokar shifter ball has this printed on it as well.
It does not hesitate at all when taking off from a dead start. No lugging or noticable straining. I guess I'm used to my 2012 Taurus having a very low RPM during hiway operation, appx. 1,600 rpm at 70ish MPH. I realize it has overdrive. I thought 2,600 RPM at 55 mph was quite high though in the vehicle in question.
