I know Ford programmed the automatic tranny to upshift as much as possible for fuel economy, but is there any way to tune the car in order to prevent the tranny from upshifting into high gears at low speeds/light throttle? I would prefer it to shift automatically for daily street use rather than use the +- buttons on the shifter. With the D or S modes, my car is all the way in 6th at 40 mph and I feel like it's lugging the engine because the RPMs are well under 1500. Is it even nnormal for the auto to go to 6th at that speed? It seems almost dangerous to drive the car that way because there's a huge lag when I need power. It's also probably not good for the engine to be lugging around town at low RPMs/high gears.
