Answer
Erica-

 Let me say, while I can't come right out and say they're ripping you off, it sounds extremely suspicious.  First of all, the knocking noise they claim should not have occured suddenly after transmission work unless they installed the transmission improperly.  Secondly, if they did in fact replace your motor, tell you it was new, and then toss a junkyard motor in there, that's fraud and it's illegal.  It also sounds as though they either didn't connect your gauges at all or did it incorrectly.  As for the computer, it's only in exceptionally rare cases that a computer is faulty.  Plus your computer does not control your locks.  I'm not sure about that year of Taurus, but I don't believe the speedometer is routed through the computer, either.  I'd check with your local better business bureau and see if there's been any complaints lodged against them and proceed from there.  Like I said, it sounds VERY suspicious.  Hope this helps.
