Will go into High gear if you manually shift it? Is the check engine light on? Regardless you may want to have the PCM scanned for any trouble codes it may have recorded. Usually iit is computer controlled item thPCM will see the failure and record a code. Does the speedo work properly?

The you may need to find a trans shop or other that has the ability to override the computer and work the solenoid for 3rd gear. Sounds like it isnt working
