P0780 on 2021 Nissan Rogue: Shift Error Causes and Fixes

What's Unique About the 2021-2021 Nissan Rogue

The 2021 Nissan Rogue (T33 generation) is highly susceptible to this specific code due to a known software glitch present from the factory. Nissan has issued multiple Technical Service Bulletins (TSBs), with NTB22-093 being the most current, that specifically address this code with a software update for both the Transmission Control Module (TCM) and the Shift Control Module (SCM). This makes the diagnostic path much more direct than on other vehicles, where P0780 might immediately suggest mechanical failure.

Symptoms You May Notice

• Check Engine Light is on
• Harsh or jerky shifting
• Delayed acceleration or hesitation
• Transmission seems stuck in a low gear ratio (high RPMs at low speed), especially during cold starts
• Whining or unusual noises from the transmission
• Vehicle enters 'limp mode' with reduced power

Most Likely Causes

1. Outdated Transmission Control Module (TCM) and/or Shift Control Module (SCM) Software 🔴 High Probability Nissan has released multiple TSBs (NTB21-023 series, superseded by NTB22-093) specifically to address P0780 on the 2021 Rogue with a software update, indicating this is a widespread, known issue.
   How to confirm: A Nissan dealer or a qualified shop with a CONSULT-III plus scan tool must check the current software part numbers on the TCM and SCM. If the TCM part number is 31039-6RA8B, 6RA8C, 6RA8D, 6RA8E, or 6RA9E, it is eligible for the update per TSB NTB22-093.
   Typical fix: Reprogramming both the TCM and SCM to the latest software version using the Nissan CONSULT tool. This is a software-only fix.
   Est. part cost: $0
2. Low or Dirty CVT Fluid 🟡 Medium Probability CVTs are sensitive to fluid level and condition. Degraded fluid can affect the hydraulic pressure needed to change ratios, triggering a shift error.
   How to confirm: Check the CVT fluid level and condition. The fluid should be at the correct level, translucent, and not smell burnt. Note: This transmission does not have a traditional dipstick, requiring a specific service procedure to check the fluid.
   Typical fix: Perform a CVT fluid drain and fill or a full fluid exchange using the correct Nissan-specified CVT fluid, NS-3.
   Est. part cost: $100-$250
3. Failing Shift Solenoid or Valve Body ⚪ Low Probability While less common than the software issue, a mechanical or electro-hydraulic failure within the transmission's valve body or of a specific shift solenoid can cause this code.
   How to confirm: If a TCM/SCM reprogram does not resolve the code, a technician would need to perform advanced diagnostics, including testing solenoid resistance and commanding solenoid operation with a scan tool.
   Typical fix: Replacement of the faulty shift solenoid or the entire valve body assembly (OEM Part Number: 3170E-28X1C).
   Est. part cost: $700-$1500

Rare But Worth Checking

• Weak or Failing Battery: A Reddit user with a 2021 Rogue reported that code P0780 appeared immediately after resolving starting issues caused by a loose terminal and weak battery in cold weather. The T33 Rogue platform is known to be extremely sensitive to low voltage, which can cause a cascade of electronic faults, including in the transmission modules.
• Internal Transmission Mechanical Failure: In the worst-case scenario, if software and valve body issues are ruled out, the code could indicate a more serious internal problem with the CVT, such as a failing pump or belt/pulley damage. This is rare but would likely require a full transmission replacement.

Diagnosis Steps

1. Connect a professional scan tool (ideally a Nissan CONSULT-III plus) to the vehicle.
2. Check for any stored DTCs in the Transmission Control Module (TCM). Confirm P0780 is present, either as 'CURRENT' or 'PAST'.
3. Check for any related TSBs. For this vehicle, TSB NTB22-093 is the primary document.
4. Using the scan tool, identify the current part numbers for the TCM and the Shift Control Module (SCM).
5. Compare the TCM part number to those listed in Table 1 of TSB NTB22-093 (31039-6RA8B, 6RA8C, 6RA8D, 6RA8E, 6RA9E). If it matches, perform the reprogramming procedure for both the TCM and SCM as instructed.
6. The reprogramming procedure requires a battery maintainer to keep voltage stable (12.0V-15.5V) and all electrical loads turned off.
7. After reprogramming, perform the DTC Confirmation Procedure outlined in the TSB: start the engine, shift to R for 5 seconds, N for 5 seconds, D for 10 seconds, and then P for 10 seconds. Re-check for codes.
8. If the software is already up to date or if the reprogram does not fix the issue, proceed with traditional diagnostics.
9. Check the CVT fluid level and condition. Ensure it is clean, at the proper level, and does not smell burnt.
10. If fluid is low or dirty, perform a fluid and filter service with Nissan CVT Fluid NS-3.
11. If the problem persists, test the transmission shift solenoids and inspect the wiring harness for damage or corrosion.
12. If all else fails, a more in-depth diagnosis of the valve body or internal transmission components is required.

Technical Service Bulletins (TSBs) & Recalls

• NTB22-093: DTC P0780 STORED IN THE TCM - This is the most current bulletin, which instructs technicians to check and, if necessary, reprogram both the Transmission Control Module (TCM) and the Shift Control Module (SCM).
• NTB21-023C: DTC P0780 STORED IN THE TCM - Superseded by NTB22-093.
• NTB21-023B: DTC P0780 STORED IN THE TCM - An earlier amendment.
• NTB21-023A: 2021 ROGUE; DTC P0780 STORED IN THE TCM - An earlier amendment that details the reprogramming procedure.
• NTB21-023: 2021 ROGUE; DTC P0780 STORED IN THE TCM - The original bulletin.
• TSB-23-23-003 (Mitsubishi): TRANSMISSION CONTROL MODULE (TCM) SOFTWARE UPDATE FOR DTC: P0780/P0706 - A TSB for the Mitsubishi Outlander, a platform mate, confirming the same software issue exists on related vehicles.

Platform-Specific Known Issues

• A series of Technical Service Bulletins (NTB21-023, NTB21-023A, NTB21-023B, NTB21-023C, and the superseding NTB22-093) were issued by Nissan specifically for DTC P0780 on the 2021 Rogue, indicating a known software problem from the factory that requires a dealer-level reprogram of both the TCM and SCM.

Mechanic-Grade Diagnostic Values

• Battery Voltage During Reprogramming — expected: Must be stable between 12.0V and 15.5V. Failure: Voltage dropping below 12.0V or rising above 15.5V can interrupt the process and damage the TCM.
• Hydraulic Pressure Test (at test port) — expected: Stable, quick pressure changes as gears are commanded.. Failure: A low, erratic, or bouncing needle on an analog pressure gauge suggests an internal hydraulic leak or, more commonly, a blockage in the valve body.

Hidden / Shadow Codes Worth Checking

• U0101: Lost Communication With TCM (see via May appear on a professional scan tool immediately after performing the TCM reprogram as specified in TSB NTB21-023A. It is considered a normal artifact of the procedure and should be erased after confirming P0780 is gone.)

Scan Tool Commands That Help

• Nissan CONSULT-III plus: Re/programming, Configuration — This is the primary function used to initiate the software update for the TCM and SCM to resolve the P0780 code as per TSB NTB22-093.
• Nissan CONSULT-III plus: Work support > ERASE LEARNING VALUE — This function is used to reset the transmission's adaptive learning values. It is performed after reprogramming or when addressing certain drivability issues to force the TCM to relearn operating parameters from a baseline state.
• Advanced Scan Tool (e.g., Launch, Autel): Write IP characterization — This is a mandatory step when replacing the CVT valve body or the entire transmission. It involves scanning a QR code on the new part to write its specific hydraulic flow calibration data to the TCM. Skipping this will result in poor shifting and likely a return of fault codes.

Wiring & Ground Locations

• Main Interior Ground — On the large steel crossmember located behind the dashboard. Can often be accessed by removing the panel next to the driver's right foot, near the HVAC frame.. A poor ground for the TCM or related control modules can cause erratic behavior and communication faults, potentially triggering codes like P0780.
• TCM Location — Mounted to a bracket on the battery tray in the engine compartment.. Provides physical access for inspection of the module and its connectors for corrosion or damage, which is a diagnostic step if reprogramming fails.
• Shift Actuator Relays (e.g., e148) — Located in a relay box under the driver's side headlight in the engine compartment.. While not a direct cause of P0780, failure in the electronic shifter control system can cause related transmission faults. Knowing the location of these relays is crucial for diagnosing no-shift or communication issues with the electronic shifter.

Real Owner Repair Stories

• Global Commerce CA YouTube Channel (2021-2024 Nissan Rogue (T33) that had been in an accident.) — No communication with the TCM, car stuck in Drive and would not start.
  ❌ Tried (didn't work) Initial scans showed communication loss, which could be misdiagnosed as a failed TCM.
  ✅ What actually fixed it The technician traced the wiring and discovered a CAN communication wire had been physically pulled out of its pin in a connector during the accident. Restoring the damaged wire and ensuring the connection was secure resolved the communication fault.

OEM Part Supersession History

• NTB21-023, NTB21-023A, NTB21-023B, NTB21-023C → NTB22-093 — The superseding Technical Service Bulletin (TSB) updated the procedure to include reprogramming for both the Transmission Control Module (TCM) and the Shift Control Module (SCM), whereas earlier versions may have focused only on the TCM.
  Heads up: Using an older TSB may not fully resolve the issue, as the SCM reprogram is now considered a required step.

Used vs. New Parts: Buying Guide for This Vehicle

When a used part is the smart pick: A used valve body or complete CVT transmission can be a cost-effective option *only* if two conditions are met: 1) The donor part is from a low-mileage, verified-working vehicle. 2) The unique QR code containing the calibration data is physically present and readable on the used part.

Donor-vehicle mileage cap: roughly under 60000 miles for the part to have meaningful remaining life.

What to inspect on the donor part:

• The QR code sticker on the valve body must be intact and scannable.
• Fluid from the donor transmission should not be black or smell excessively burnt.
• When the pan is dropped, magnets should have only a fine metallic paste, not large metal chunks or shavings.

OEM-only on this vehicle (don't cheap out):

• CVT Fluid (Nissan NS-3): CVTs are extremely sensitive to fluid properties. Using non-specified fluid is a leading cause of failure.
• Transmission Control Module (TCM): A new TCM must be programmed to the vehicle's VIN by a dealer. A used TCM is often locked to the donor vehicle's VIN and may not be reprogrammable, making it a very risky purchase.

Brands owners have reported issues with on this vehicle:

• Any CVT fluid that is not explicitly Nissan NS-3 or a fully licensed equivalent. Universal or 'multi-vehicle' CVT fluids should be avoided.
