Simply adding fluid will cause more harm (more is not better in this case).
Assuming that it hasn't been done in a while, take your car to a mechanic
and have the fluid and screen changed before more damage is done. Then
assess if the tranny is slipping.
Reverse not working us *usually* a sign that it's new tranny time. You
could try changing the oil and filter - that's cheap and easy to do.
But be prepared to find a good used trans or have it rebuilt.
