P0744 on a Nissan means the torque converter clutch is engaging and disengaging erratically inside the CVT. Unlike traditional automatics, Nissan CVTs lock the torque converter early and keep it locked during most driving. When that lockup becomes intermittent, the resulting friction heat starts a cycle that degrades CVT fluid and can destroy the transmission.

What Does P0744 Mean on a Nissan: Quick Diagnostic Intelligence
P0744 stands for Torque Converter Clutch Circuit Intermittent. On Nissan vehicles equipped with a Jatco CVT (continuously variable transmission), the torque converter works primarily as a launch device to get the vehicle moving from a stop. Once moving, the CVT belt or chain system handles ratio changes. The torque converter clutch locks up early and stays locked during most driving to reduce heat and improve fuel economy.
The Transmission Control Module (TCM) monitors slip speed, which is the difference between engine RPM and transmission input RPM. P0744 triggers when slip speed exceeds a calculated threshold (roughly 40 RPM plus half the vehicle speed) while lockup pressure is above 0.2 MPa for more than 30 seconds continuously.
This code is more serious on Nissan CVTs than on traditional automatics. Intermittent lockup generates friction heat, and Nissan CVTs are extremely heat-sensitive. The heat degrades the CVT fluid, which causes more slippage, which generates more heat. This vicious cycle can lead to complete CVT failure if ignored.
Which Nissan Models Get P0744 Most Often?
P0744 appears most frequently on Nissan models equipped with the smaller Jatco CVT units. The Altima, Sentra, Rogue, Kicks, and Versa lead in reported cases. Peak failure years are 2007 to 2008 and 2013 to 2018, which align with the first and second generation Jatco CVT designs.
| Model | Years Most Affected | CVT Type (Jatco) | Frequency |
|---|---|---|---|
| Nissan Altima | 2007-2008, 2013-2016 | JF011E, JF016E | High |
| Nissan Sentra | 2007-2008, 2013-2017 | JF011E, JF015E | High |
| Nissan Rogue | 2008, 2013-2018 | JF011E, JF016E | High |
| Nissan Kicks | 2018-2021 | JF015E | High |
| Nissan Versa / Versa Note | 2012-2020 | JF015E | High |
| Nissan Pathfinder | 2015-2018 | JF017E | Moderate |
| Nissan Murano | 2009-2014 | JF010E | Moderate |
| Nissan Maxima | 2007-2008 | JF011E | Moderate |
| Nissan Juke | 2013-2017 | JF015E | Moderate |
Common Causes of P0744 on Nissan CVTs
The causes below are ranked by how often each one triggers P0744 on Nissan vehicles, based on TSB data, NHTSA complaints, and technician reports from transmission specialty shops.
1. CVT Fluid Degradation (About 40% of Cases)
Degraded CVT fluid is the single most common cause. Nissan CVT fluid breaks down faster than conventional automatic transmission fluid, especially under heat stress. Dark, burnt-smelling fluid loses the friction properties needed for reliable torque converter lockup. Many owners exceed the recommended service interval of 30,000 miles for severe-duty driving. Using the wrong fluid specification is also a major trigger.
2. Valve Body Wear (About 25% of Cases)
Jatco CVT valve bodies have bores that are prone to premature wear. Worn bores cause internal fluid pressure loss, which leads to inconsistent torque converter clutch engagement. TSB NTB0-148a documents this specific failure pattern on 2007 to 2008 Altima, Sentra, and Rogue models. Aftermarket rebuild kits with oversized valves are available for this repair.
3. TCC Solenoid Failure (About 15% of Cases)
The torque converter clutch solenoid is integrated into the valve body. Electrical failure or contamination from metal debris in the CVT fluid can cause intermittent operation. On some models, the solenoid is accessible without removing the transmission by dropping the pan.
4. TCM Problems (About 10% of Cases)
The Transmission Control Module can develop software glitches that send erratic lockup commands. Several Nissan warranty extensions specifically include TCM reprogramming as part of the repair. Water intrusion can also damage the TCM, which is often mounted low on the vehicle.
5. Wiring and Connector Issues (About 5% of Cases)
Corroded connectors at the transmission harness, chafed wiring near exhaust components, or poor ground connections can mimic solenoid failure. Always inspect wiring before replacing components.
6. Internal CVT or Torque Converter Failure (About 5% of Cases)
Worn friction material in the torque converter or metal debris from belt and chain wear can contaminate the TCC circuit. At this stage, full CVT replacement is typically required.
NS-2 vs NS-3: The CVT Fluid Mistake That Kills Transmissions
Nissan uses two different CVT fluid specifications, and using the wrong one is a documented cause of P0744.
| Specification | Color | Model Years | Key Detail |
|---|---|---|---|
| NS-2 | Green | 2007-2012 CVTs | Higher viscosity for first-gen Jatco units |
| NS-3 | Blue | 2013 and newer CVTs | Lower viscosity for redesigned internals |
NS-3 is generally backward-compatible with NS-2 applications. However, NS-2 should never be used where NS-3 is specified because the newer CVTs require a lower viscosity fluid. Using generic automatic transmission fluid or conventional transmission fluid in any Nissan CVT will cause rapid failure. If you are unsure which fluid your vehicle requires, check the owner’s manual or the label on the CVT dipstick (if equipped).
Is Your Nissan Covered? CVT Warranty Extensions
Nissan has issued multiple CVT warranty extensions across different model years, primarily as a result of class action lawsuit settlements. These extensions specifically cover the torque converter components relevant to P0744. Check your VIN at a Nissan dealership to confirm eligibility.
| Coverage Group | Models | Extended Coverage | Settlement |
|---|---|---|---|
| 2003-2010 models | Altima, Murano, Maxima, others | 10 years / 120,000 miles | Early CVT program (transferable) |
| 2012-2017 sedans | Versa, Juke, Sentra, Altima, Versa Note | 84 months / 84,000 miles | Martinez v. Nissan |
| 2014-2018 SUVs | Rogue, Pathfinder, Infiniti QX60 | 84 months / 84,000 miles | Stringer v. Nissan |
| 2017-2019 newer models | Altima, Sentra, Versa, Versa Note | 84 months / 84,000 miles | Extended warranty program |
All warranty extensions cover the CVT assembly, valve body, torque converter, gaskets and seals, and TCM reprogramming. Rental vehicle coverage is included during repairs. If you already paid out of pocket for a CVT repair on a covered model, you may be eligible for reimbursement by contacting Nissan at 800-867-7669.
Nissan TSBs for P0744
Nissan has issued several Technical Service Bulletins addressing P0744 and related CVT torque converter issues.
| TSB Number | Models Affected | Issue | Fix |
|---|---|---|---|
| NTB0-148a | 2007-2008 Altima, Rogue, Sentra | Valve body bore wear causing pressure loss | Replace valve body, reprogram TCM |
| NTB10-016 | 2009-2010 Cube, Versa | MIL illumination with transmission DTCs | Diagnostic procedure, component replacement |
| NTB19-040 series (a through H) | 2018-2021 Kicks | P0744 with hesitation and reduced power | Flowchart may result in CVT replacement |
| NTB22-021 | 2018-2021 Kicks | CVT-related codes including P0744 | Per bulletin procedures |
Always ask the dealership or your technician to check for applicable TSBs before starting diagnosis. A TSB can save hours of diagnostic time and may qualify the repair for warranty coverage.
How to Diagnose P0744 on a Nissan
Follow these steps in order. Each step narrows the possible causes before moving to more expensive diagnostics.
Step 1: Scan for All Codes
Use an OBD-II scanner capable of reading manufacturer-specific codes. Record all stored DTCs, pending codes, and freeze frame data. Pay attention to companion codes because they reveal the scope of the problem. P0744 alone usually points to fluid or solenoid issues. P0744 combined with P0840 or P0845 indicates valve body pressure problems. P0744 with P1778 on 2007 to 2008 models typically means internal CVT failure.
Step 2: Check CVT Fluid Level and Condition
Check fluid at operating temperature per dipstick markings (some models have no dipstick and require a dealer scan tool). Fresh NS-2 fluid is green; fresh NS-3 fluid is blue. Dark brown fluid with a burnt smell means the fluid has broken down. Metal particles on the drain plug magnet indicate internal wear. Milky fluid means coolant contamination, which is a serious problem requiring immediate attention.
Step 3: Check TSBs for Your Model and Year
Look up applicable Technical Service Bulletins before general troubleshooting. If a TSB matches your vehicle, follow its diagnostic flowchart rather than the general procedure below.
Step 4: Test the TCC Solenoid
Locate the TCC solenoid (integrated into the valve body, accessible from the transmission pan on some models). Measure resistance with a multimeter. The reading should be between 10 and 25 ohms at room temperature. Apply 12 volts directly to verify the solenoid clicks. Inspect the solenoid screen for metal debris.
Step 5: Check Wiring and Connectors
Inspect the transmission harness connector for corroded pins, bent pins, or damaged locks. Check wiring for chafing near exhaust heat shields. Verify ground connections and measure continuity from the TCM connector to the transmission connector.
Step 6: Road Test With Live Data
Connect a scanner with live data capability. Monitor engine RPM versus transmission input RPM (the difference is slip), TCC solenoid duty cycle, CVT fluid temperature, and line pressure. Drive at a steady 40 mph or higher for at least 30 seconds. Normal operation shows near-zero slip when the TCC is commanded on. Watch for intermittent RPM fluctuations that indicate the TCC is dropping in and out.
P0744 Repair Costs on Nissan
Costs vary significantly depending on the root cause. A CVT fluid change is the least expensive fix and resolves about 40% of cases. Full CVT replacement at a dealer can exceed $8,000. Independent transmission shops typically save $1,000 or more compared to dealer pricing.
| Repair | DIY Cost | Independent Shop | Dealer |
|---|---|---|---|
| CVT fluid drain and fill | $80-$120 | $200-$350 | $250-$400 |
| TCC solenoid replacement | N/A | $250-$600 | $400-$800 |
| Valve body replacement | N/A | $800-$1,500 | $1,200-$2,500 |
| TCM replacement | N/A | $500-$1,000 | $800-$1,500 |
| Full CVT replacement (reman) | N/A | $3,500-$5,500 | $5,000-$7,500 |
| Full CVT replacement (new) | N/A | N/A | $6,000-$9,000 |
Before paying for any repair, check your warranty extension eligibility. Many 2003 to 2019 models have extended CVT coverage that includes the torque converter. If you already paid out of pocket for a qualifying repair, file for reimbursement through Nissan.
Can You Drive With P0744?
Minimal driving only. P0744 on a Nissan CVT is not a “monitor and drive” code. Intermittent torque converter lockup generates friction heat that accelerates CVT fluid degradation. The Martinez v. Nissan lawsuit documented that Nissan CVTs have undersized transmission coolers, which compounds the heat problem. Extended highway driving with an active P0744 code is the fastest path to complete CVT failure. Drive only to the shop for diagnosis.
What Companion Codes Reveal About the Root Cause
The codes stored alongside P0744 provide important diagnostic clues. Here is what common combinations mean on Nissan CVTs.
| Code Combination | Likely Root Cause | Typical Repair |
|---|---|---|
| P0744 alone | CVT fluid degradation or TCC solenoid | Fluid change or solenoid replacement |
| P0744 + P0840/P0845 | Valve body pressure loss | Valve body replacement |
| P0744 + P1777/P1778 | CVT step motor plus TCC failure (07-08) | Internal CVT repair or replacement |
| P0744 + P0741 + P2857-P285A | Factory-defective CVT (Kicks, 2020 Versa) | CVT assembly replacement under warranty |
| P0744 + multiple transmission codes | Electrical failure or major internal damage | Full diagnostic, likely CVT replacement |
