What will keep my Neon from shifting if the transmission is okay?

What will keep my Dodge Neon from shifting gears, if there is nothing wrong with the transmission? This is a 2002 Dodge Neon and I was told it could be a computer problem. If the computer is bad, can I replace it with a computer from a wrecked Neon. Also, I was told it could be because of a bad cluster board, could this keep the car from shifting gears?

you could replace the computer from a wrecked neon but its hard to tell if it has been damaged I think dodge can actually reprogram it if you bring it in "THEY SHOULD DO IT FOR FREE"
