I have 2011 with penstar v6 and it seems the shift points are high. for example shifting from first to second gear it shifts at 3500, that just seems high. when driving 25 mph and lower it feels like its it should have shifted into second gear but stays in first. I just got the truck a month ago so maybe I am not use to the 5 speed. Is it normal to shift into second at 3000 + rpms?
