my car is not going into reverse on 2001 Chevrolet Metro

I turn my car on and it doesnt go into reverse. The other gears work and the car rolls back when i put it into neutral so it isnt the emergency brake. I put two quarts of transmission fluid in because it had none. Why is this happening? Whats wrong with it? How much to fix it?

If it was that low on fluid, the transmission may have been damaged. These problems are better off in the hands of a qualified transmission shop. Try to find an ATRA shop in your are or another that rebuilds transmissions.
