Thanks for the update. Click on this link for the troubleshooting manual. Troubleshooting

Try to run through the power up sequence tests and the fault retrieval procedures and see if you can get it to display fault codes

Expert:  Daniel Wilson replied 1 year ago.

If it is jammed in 10th it is highly unlikely there would not be any codes unless the TCM is not communicating from no power or ground, harness issue, or failed TCM. Let me know

The info I posted has all the detailed test info for each fault

Ya I've already been through that Eaton troubleshooting guide

Do you have a test TCM you can try? Verify power and ground to the TCM and if ok and the harness and connector pins test good Id try a test TCM or have that one reflashed /bench tested and see if your problem resolves. Especially since you have no codes
