Not moving forward or backward in any gear

The description sounds like possibly a CV axle failure, Especially as the axles used on these cars has a large damper molded onto them. If you live in an area where rust is an issue it would be the first thing I would check. To do that you need to get the front of the car high enough that you can go underneath it and physically grab the axles and see if they are broken. What can happen is the axles will rust at the spot the damper is attached. Then you shift into gear and the spot is weak enough that it snaps off. The rubber then holds it in place and it looks okay, until you pull on it and see the axle bend where it shouldn't.
Another possibility is that something inside the transmission has failed, however I'd check the axles first.
