Has it been scanned for codes yet? If not, that would be the best starting point. We need to see if there are any codes pertaining to transmission operation. Another thing that comes to mind is the trans temp sensor. If this reading is out of range low (Showing freezing temperatures) it could inhibit shifting into overdrive. You would need a factory scanner or equivalent to monitor the temperature sensors.
Also, if you post any codes that were retrieved, I can help you get this figured out...
Keep me posted...
