HELP - car won't shift into any gear at all / no symptoms prior / one car family

WEll, we have talked about replacing the steering column, overhauling the transmission, and about the space shuttle burn-up. Now can we hear what the problem really was??

This same thing just happen to a friend of mine with his Taurus. He left his house and when he got to the corner it would not move. It turned out to be the pump shaft in the transmission. His trans guy replaced the shaft and its been fine.
Congrats on the baby.
