This depends on which transmission the car has. If this is the four-speed, it will use the transmission range sensor and the computer to turn on the appropriate dash light. If that sensor has a defect, the transmission should be in limp mode, (stuck in second gear).
The older cars with the really tough three-speed transmission have an adjustment under the dash for the shift indicator.
