The car will not drive or reverse. The gear shift moves fine. The car just wont move

What is your question?

I've checked the transmission fluid its fine. There is no noise. Usually when the car starts warming up it does not want to move. Well tonight being a cold night its still not moving. The gear shifts but no movement in car. I've tried cutting the car off waiting ten, then fifteen then twenty seconds before starting and trying again. This has been going on for one month. No leaks anywhere. When I shift into drive there is no nudge showing the car wants to move. I Hope its not the whole transmission getting ready to go out.

What makes this problem better or worse?

Worse when heat is running and the temperature gage is warm
