Why is my car revving without me touching the gas?
This is a common problem when the idle air control module is not functioning as it should. This is a component that helps to monitor air/fuel mixture at idle speed. When this is not working properly, this causes an imbalance in the air/fuel mixture resulting in intermittent or abnormal idling as you’ve described.

Can I just add transmission fluid?
You can add more by inserting a funnel into the tube the dipstick was withdrawn from and pouring a small amount of automatic transmission fluid into the pipe. Check the level each time you add a little until the level is right between the two lines.
