How to diagnose and fix P0744: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Nissan NV200 · 2013–2021
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.
Common Symptoms
- Jerking or shuddering during acceleration
- Delayed engagement from Park to Drive or Reverse
- Whining noise that increases with speed
- RPM fluctuation without speed change
- Complete loss of forward or reverse drive
How to Fix
Change CVT fluid every 25,000 miles with Nissan NS-2 CVT fluid — more frequently than the recommended interval given commercial use patterns. If shuddering begins, an immediate fluid change may extend life. When replacement is needed, a remanufactured CVT ($2,500-$3,500) is more economical than a dealer unit. Consider aftermarket CVT coolers for delivery vehicles.

Owner tips & cautions
- TipInstall an aftermarket CVT transmission cooler if you use the NV200 for delivery work — it significantly extends CVT life.
- WarningDo not exceed the NV200's payload capacity (1,480 lbs) — overloading dramatically shortens CVT lifespan.
- TipChange CVT fluid every 25,000 miles for commercial use rather than the 60,000-mile factory interval.

Citroen C3 · 2003–2016
C3s fitted with Citroen's automated-manual gearboxes — SensoDrive on the C3 I, then EGS6/ETG6 on later e-HDi and PureTech cars — suffer well-documented failures of the electronic clutch actuator, gear actuator and gearbox ECU. Worn actuator motors and clutch-position adaptation errors cause violently jerky gearchanges, refusal to select gears, gearbox warning messages with the box locked in gear (limp mode), and in some ECU failures a car that will not start. Specialist rebuilders describe the actuator and ECU faults as inherent design weaknesses, and repairs at a dealer can run from several hundred to several thousand pounds.
Common Symptoms
- Jerky or violent gearchanges
- Gearbox warning light or message, stuck in one gear (limp mode)
- Refusal to select gears from neutral
- Engine will not start (gearbox ECU fault)
- Juddering when pulling away
- Delayed engagement of drive or reverse
How to Fix
Have the stored fault codes read by a PSA specialist: failed clutch/gear actuators can be rebuilt or replaced and the clutch self-calibration relearned, while gearbox ECUs can be tested and rebuilt by specialists at far less than dealer replacement cost. A worn clutch must be replaced and the actuator recalibrated at the same time.

Nissan Rogue · 2014–2018
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.
Common Symptoms
- Shudder or judder during light acceleration 25-45 mph
- Rubber-band feeling / hesitation from a stop
- High RPM with little forward movement
- Sudden loss of power / limp mode at highway speed
- Transmission overheating warning
- Jerking or stalling at stops
How to Fix
Check for an active CVT warranty extension (84mo/84k from original sale on 2014-2018 Rogue) and have the dealer replace the CVT at no charge if eligible. Out of warranty, a remanufactured unit at an independent shop typically runs lower than a new OEM CVT at the dealer. A CVT software/valve-body update or fluid service (NS-3 fluid) can mitigate early judder; codes P17F0 (CVT judder) and P17F1 (chain slip) confirm the failure mode. Submit class-action claim paperwork for reimbursement of prior CVT repairs.

Frequently asked questions
What does P0744 mean?
P0744 stands for "Torque Converter Clutch Circuit Intermittent." 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.
What are the most common causes of P0744?
The most common causes of P0744 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0744?
Repair costs for P0744 range from $200 to $8,000, depending on the vehicle and root cause.
