I will assume that you have a 95, since newer models don't have a cable.
The cable is in two pieces, The part from the transmission to the firewall is the only part I have replaced.
Take off the wiper arms and grille in front of the windshield. Squeze the plastic connector and pull it off, the transmission end has a threaded connector. Replace the O-ring if damaged.
You will likely have to remove the instrument cluster to get the other piece of cable out.
