Low speed high rpm

What is your question?

Everything seems fine. But when accelerating, i have to press pedal half way in and engine seems to be forced and puts high rpms but starts very slowly to move. To maintain speed at 75mph I have to press pedal half way in, rpms to 3000 to stay at 75mph. At 85 mph rpms go to 3500. At deceleration, speed drops quickly to almost complete stop without brakes. While in park position, engine idles perfectly. No noises, no leaks, no burnt smells.

What makes this problem better or worse?

It doesnt matter. Hot or cold problem exists

How long has your 2009 Chrysler Aspen had this problem?

Just yesterday
