Diagnostic Trouble Code 0804 is detected when the signal from the Transmission Control Module is not sent to the Engine Control Module. The factory service manual identifies these possible causes:
- Harness or connectors (the communications line circuit between ECM and TCM is open or shorted.)
- TCM
- Weak or dead battery

Did you ever fix the problem and what happened? I also got this code 0804 yesterday when power from my car's battery was drained all of a sudden.
