You've got a hard-metal linkage issue, in my opinion. Should be no problem for the car to shift into forward gear coming out of the garage unless there is a rigid shifting disconnect somewhere.

Even without enough fluid, vacuuum, etc, you should be able to shift the tranny into forward gear and move it for a while down the driveway.

Luckily, there are a bunch of automatic gurus here that will clear this up for you rather quickly.
