2021 Nissan Rogue DTC P0780 in TCM TSB Superseded

This document, Nissan Technical Service Bulletin (TSB) NTB21-023C, concerns the diagnostic trouble code (DTC) P0780 stored in the Transmission Control Module (TCM) for the 2021 Nissan Rogue (T33). This bulletin, dated October 27, 2022, serves primarily as a notification that it has been superseded by a newer bulletin, NTB22-093, which also addresses the "DTC P0780 STORED IN THE TCM" condition.

Understanding DTC P0780

When a Nissan Rogue DTC P0780 is stored in the Transmission Control Module (TCM), it generally indicates a malfunction in the shift control system. This code specifically points to a "Shift/Gear Error" or "Shift Control System Malfunction." The TCM is responsible for managing the transmission's gear changes, and a P0780 code suggests that the module has detected an issue with the expected gear ratio or shift timing. This can lead to various transmission-related symptoms, though this particular bulletin does not detail them.

The Superseded Bulletin: NTB21-023C

Nissan TSB NTB21-023C, with classification AT21-003C, was originally published to provide guidance for technicians diagnosing and repairing the Nissan Rogue DTC P0780. However, as of October 27, 2022, this version of the bulletin is no longer current. It has undergone several revisions since its initial publication on March 16, 2021, with updates to "Table A on page 8" on March 19, 2021, and August 30, 2022. The final revision, NTB21-023C, explicitly states that the bulletin is superseded.
