Evening, the symptoms you are describing is a locked up torque converter. The reason for the torque converter being locked up could be the torque converter itself or internal trans issue such as the valve body. To be certain its not electrical.....I recommend disconnecting the electrical connector going into the transmission. It located on the drivers side and the connector is vertical. The other connector on the trans is the park/neutral switch and its on the side of the trans. Its connector is horizontal. Once disconnected, start the truck and see if the torque converter is still staying locked up. If so then the issue is mechanical and not electrical.
