There should be a plug in on the trans somewhere. Look on there for a plug in missing a plug and find the plug and place the two together and Voila!

Lindsaymmo5, The transmission has a speed sensor on it that sends a signal to the PCM then to the speedo. As mentioned, it is most likely disconnected or damaged. If you changed the transmission with a different year, that could be a problem.
