The 4-HP22EH transmissions can have electrical issues and to start with I would check fluid level and condition. At that mileage the history of maintenance is a concern. Also the issue you have might be electrical, checking the connections would be a step I would take, check the dash board indicator lights for proper operation and the connector at the transmission. Lets start with these items and let us know how it goes mate!
