Car will not move on the "D" gear unless the "OD" is off.

What is your question?

The car will not drive when drive gear is selected. However, when I start with the first gear and gradually move to the "D" at forty miles, it will continue moving until I get to a stop sign. The only other time it will move is when the "OD" is off. This is a daily problem. What could possibly be the problem.
