P0744 on Nissan
Torque Converter Clutch Circuit Intermittent
P0744 on Nissan vehicles indicates torque converter clutch circuit intermittent. Au7o has documented this code across 5 Nissan models — most commonly on Altima, Armada, NV200. This code means the transmission computer detected an intermittent (on-and-off) problem with the torque converter clutch (TCC) circuit. The torque converter clutch locks up to create a direct mechanical link between the engine and transmission at cruising speed, improving efficiency, and the computer monitors that circuit and the converter's slip. When the lockup signal or engagement comes and goes erratically, this code sets. Drivers often feel shuddering, slipping, or surging at steady speeds, or the engine RPM may flare; it points to an electrical, fluid, or mechanical fault in the lockup system. Typical repair costs on Nissan range from $200 to $8,000, depending on the specific model and root cause.
Common Causes of P0744
- •Low, dirty, or degraded transmission fluid
- •Failed or stuck torque converter clutch solenoid
- •Intermittent or chafed solenoid/TCC wiring
- •Corroded or loose transmission connector
- •Worn torque converter or internal clutch
- •Clogged valve body passages or sticking valve
- •Faulty transmission control module (TCM)
P0744 on Nissan by Model
Nissan Altima(1 issue)
- P0741 — Torque Converter Clutch Stuck Off from JATCO CVT Lockup/Valve Body Fault2007-2018
The Altima's JATCO continuously variable transmission (RE0F10-series) uses a torque converter with a lockup (TCC) clutch, and P0741 sets when the TCM detects an rpm slip mismatch showing the lockup clutch is not engaging as commanded (stuck off). On Altima CVTs the code is commonly driven by degraded/overheated CVT fluid, a worn or sticking lockup control solenoid, or a valve body whose bores wear and leak line pressure so the TCC can't hold. On earlier RE0F10A units (notably 07-08) the valve body is prone to internal leakage, and Nissan bulletins have at times directed full CVT replacement when P0741/P0744 appears with lockup shudder. Drivers feel a shudder or judder under light acceleration (roughly 25-45 mph), rubber-band hesitation, higher-than-normal cruising rpm, and sometimes a slight surge as the converter fails to lock.
Nissan Armada(1 issue)
- Radiator Internal Transmission Cooler Rupture Mixing Coolant Into ATF2004-2015
The TA60 radiator has the automatic transmission cooler built into the bottom tank, with coolant and ATF separated only by a thin internal wall. That wall cracks with age and thermal cycling, letting coolant push into the transmission circuit. The resulting pink, milky ATF - owners call it the strawberry milkshake - swells and delaminates the clutch friction material and destroys the RE5R05A within a few hundred miles of driving. The failure is frequently silent until shifting goes bad, and the same rupture can also push ATF into the cooling system. The factory spring clips on the cooler line-to-radiator joints are a second, separate leak point.
Nissan NV200(1 issue)
- CVT Transmission Failure Under Commercial Use2013-2021
The NV200's Jatco CVT transmission is particularly prone to failure when used for commercial delivery work, which is the vehicle's primary purpose. The constant stop-and-go driving and heavy loads accelerate CVT belt wear and valve body degradation. Many owners report failure between 60,000-100,000 miles. Symptoms include jerking during acceleration, delayed shifting, and eventually complete loss of drive.
Nissan Rogue(1 issue)
- JATCO CVT judder, shudder, slipping and complete failure2014-2018
The second-generation Rogue uses a JATCO continuously variable transmission (RE0F10x family) that is widely documented to judder/shudder during light acceleration (typically 25-45 mph), exhibit a 'rubber band' rubbery hesitation from a stop, overheat into limp mode with sudden loss of power at highway speed, and in many cases fail completely before 100,000 miles. CarComplaints lists 111+ power train complaints for the 2014 model alone (severity 10/10), and Nissan accumulated well over 1,000 transmission-related NHTSA complaints across the generation. A class action (Stringer v. Nissan / related Rogue-Pathfinder-QX60 settlement, final approval March 2022) extended the CVT warranty on 2014-2018 Rogues from 60mo/60k to 84mo/84k miles and provided repair reimbursement.
Nissan Sentra(1 issue)
- P0741 — Torque Converter Clutch Stuck Off from CVT Lockup Solenoid / Valve-Body Wear and Degraded CVT Fluid2013-2019
The B17 Sentra's Jatco CVT (JF015E / CVT7, RE0F11A) uses a torque converter with a lockup clutch, and P0741 is set when the TCM sees the converter clutch failing to lock (input-shaft vs converter speed difference exceeding threshold). On these Nissan CVTs the lockup solenoid lives in the valve body, and the Jatco valve-body bores are prone to wear that causes pressure leakage and sticky solenoid/valve movement; degraded or overheated CVT fluid full of clutch material makes it worse. Drivers commonly feel a shudder/judder at light throttle, and on this transmission P0741 frequently appears alongside related lockup/judder codes such as P0744 and P17F0.
