After driving my new JK for over 1100 miles now, I have gotten to know it fairly well. It has what I call a "flat spot" in the accelleration curve at right about 55 MPH in high gear. I mean probably 3/4-1" of pedal travel where the Jeep does NOTHING. It is especially noticable uphill. It will actually lose speed instead of staying steady. If I continue depressing the pedal, it will of course downshift (automatic) and begin accellerating again. Is this normal?

 

Yep, it is the computer trying to maximize fuel economy, it is drive by wire

 

Do you have an auto? When getting on the freeway I always have to hit the OD off button because it seems the tranny wants to drop into OD right about the time I need to merge into traffic, and when it does there is no gusto at all.
