The transmission will not shift into any gears on 94 Corolla? on 1994 Toyota Corolla

Just purchased the car a few weeks ago and it ran great. All of a sudden, the tranmission will not shift. I was told it had a new transmission in it but no other details. I was also told it might be a shift sylenoid (sp.?) I'm worried about repair costs if it is the sylenoid. Advice or recommendations great appreciated.

Can you put it in "D" or is the shifter stuck in "P"?

Automatic, I'm guessing?
