New members and seasoned Nissan owners alike may encounter transmission-related challenges, and in this discussion, we explore issues reported by two Nissan Altima owners. While the symptoms and error codes may vary slightly, a common thread emerges, shedding light on potential causes and solutions.
Transmission Woes at 2000 RPM
The first owner, with a 2010 Nissan Altima 2.5 boasting 205,000 miles, describes a jerking sensation during acceleration. The problem seems most pronounced at around 20-25 mph, reminiscent of a manual transmission starting in a higher gear. The diagnostic trouble codes (DTCs) retrieved include P1701, P0826, P0744, P0725, U1002, and P0101. The mechanic’s diagnosis points towards a failing ‘torque converter clutch solenoid.’ The check engine light is illuminated, signaling the urgency of addressing this issue.
Decoding P0744 in a 2010 Nissan Maxima
In the second account, a 2010 Nissan Maxima owner encounters the P0744 code, specifically related to the torque converter clutch. The potential culprits include dirty transmission fluid, poor wire connection, or a faulty control solenoid. Driving with a P0744 code is cautioned against, as it may affect the transmission’s ability to shift and accelerate properly.
Diagnosis and Insights
The mix of symptoms from both articles paints a broader picture of the transmission challenges faced by these Nissan Altima owners. The commonality in the P0744 code suggests a shared issue related to the torque converter clutch.
Torque Converter Clutch Solenoid: A Common Culprit
Both owners mention the torque converter clutch solenoid as a likely suspect. In the first article, the mechanic pinpoints this component as the cause of the jerking sensation during acceleration. The second article reinforces this by attributing the P0744 code directly to the torque converter clutch.
2010 Nissan Altima 2.5
The first owner shares experiences of the car’s behavior, emphasizing that the issue disappears after reaching speeds above 25 mph. This valuable insight provides context for the mechanic’s diagnosis and highlights the importance of considering symptoms at various driving conditions.

The second owner’s experience with the P0744 code raises concerns about driving with this issue. While it’s deemed safe to drive back home, the potential impact on transmission functionality is a cause for caution. This insight adds a layer of urgency to addressing the problem promptly.
Possible Solutions and Considerations
Transmission Fluid Condition
Article 2 draws attention to the role of dirty transmission fluid in triggering the P0744 code. While the fluid in the 2008 Altima is noted as dirty, the owner hesitates to change it due to concerns about the CVT’s known issues. This dilemma raises questions about the significance of fluid quality in addressing transmission issues.
