My E250 work van has the 4.6 and anyone who owns one knows the impossibility of staying in a low RPM range for very long.

Maybe you need to adjust your transmission shift points?

I don't go over 2,000 RPM when driving in the city, but accelerating onto the highway is a different story. And no, my shift points are normal. I believe it has a 3.55 final drive like most F-150's with the 4R70W tranny.

Yeah, I can imagine.

I try to stay below 2k around town for gas mileage reasons (not always successful).

Interesting.....

Mine's newer (2008) so it has the 4R75E trans. I have 3.73's but 31" tires

I've done a lot of driving these last few days, even some "spirited" (gettin' goin' sooner) and still never saw over 2400 rpm. Cruises about 1800 at 65, kicks down on hills with the A/C on and jumps up to 2250
