RE: 70 mph
Dude, i was also wondering why i have this same problem. I have a 2001 SE and at 60 i have 2500 and just like Mike, 70mph also makes 3000 rpm. i was just thinking it was only my car have problems but i guess it's a common thing. I worry that this higher rpm is making our cars less fuel effiecient than if it were to be 500 rpm less.

RE: 70 mph
Here is a good quote I got in another forum that explains a bit more about the 3 and 4 speed deal.
The 4 speed trans will have a circle around the D.The 3 speed trans will simply have a D (no circle).If your car does have the 3 speed ,a 6 cylinder is a 670,and a 4 cylinder is a 470.The Overdrive is the 42TE,also known as the 604.When i said a 3 speed is a 1 to 1 ratio,that is exactly correct for an old RWD car like a RoadRunner,Nova,etc.It is slightly different on a transaxle,even a 3 speed one,as Chrysler takes the 1 to 1 ratio of the rotating assembly,same as the old musclecars,and ramps it up slightly with a big gear and a smaller gear,much like bicycle sprockets.The smaller gear makes the pinion spin ever so sligthly better than the 1 to 1 ratio.You feel two shifts,1st to 2nd gear,then 2nd to 3rd gear,then on the 3 speed trans,you feel the clutch apply in the torque convertor,also known as TCC for Torque Convertor Clutch.This apply feels like a 3rd shift in some cars as the engine Rpm's can drop 200-500 Rpm's.As for the two different yet similar cars,tire diamter can dramatically alter a vehicles cruising Rpm's,better or worse.In addition,transfer gears are available with different tooth counts for varying final drive ratios depending on the weight and horsepower of the car.
