I feel bad for your situation.
I dont think selling it would be a viable option at this point. You would be lucky to get $1400 for the car if the transmission isnt working, especially in that it is an Impreza transmission. So breaking even would be somewhat difficult. I would recommend you search your local salvage yards for a SVX transmission and get everything back to the way it should be. You'll be better off in the long run IMO.
Best,
Mike
