Something my cousin told me: set your cruise; Slowly accelerate to about 8-10k or so higher(don't let it kick down), hold it there for about a 3 count; let off the accelerator, the rpm will drop about 2-400rpm.
Seems to be a two stage torque coverter near as I can figure. whatever, it turns that 5.7 hemi into an honest 25-28mpg highway cruiser. Seriously, try it.
Don't know why it's not in the owners manual; we have a 2006; love it. Only complaints, the seats are a little, "hard", and the wheel could be back about 2".
The 5.7 hemi's not, "race car" acceleration, but if you punch it, it's there; couple that with good gas mileage and it's hard not to love it.
