Automatic Transmission Control Module problems of the 2019 Nissan Titan

The torque converter on my 2019 Nissan Titan pro-4x failed at approximately 60,000 miles. Symptoms began as cold-start shudder lasting several minutes, progressing to pronounced shudder under light throttle acceleration between 25–50 mph, erratic shifting at the 3-4 and 4-5 gear transitions, and tcc (torque converter clutch) slip. These symptoms created unpredictable drivetrain behavior at highway speeds, presenting a safety risk to myself and other drivers. The problem was diagnosed and confirmed by an independent service center using live pcm data. Tcc slip readings of -27/748 rpm were recorded during a test drive, matching the failure criteria specified in Nissan technical service bulletin ntb22-099a, which Nissan issued to address this exact torque converter defect in this model. The repair — torque converter remove and replace using oe parts — is currently underway. The failed component is available for inspection upon request. Warning symptoms (cold-start shudder and light-throttle shudder) were present for approximately one month before the failure became undriveable. Nissan was contacted regarding the known defect and declined to provide assistance, citing warranty expiration. The TSB coverage window for this defect expired approximately eight months before symptoms became acute.
