You said any input so we had our trany fail on one of our beaters it wouldn't go in reverse at all and did exactly what you described (minus the 4x4 light).
You should try reverse and see if that does anything.
Good luck let us know how it turns out.
*oh our repair was a brand new tranny free cause we were under warranty.
