Let me know if you are able to determine an electrical issue. However, it sounds like it could be related to a wiring harness issue or a line pressure issue. I recall from years ago, there was a technical service bulletin (TSB) related to hard or no shift. The harness to the transaxle was replaced as a fix.
If you are unable to determine if it is an electrical issue, let me know. Also, let me know the specific codes stored.
