350Z Automatic Transmission Torque Converter Failure

Esteemed Nissan aficionados, I come to you with a heavy heart and a vexing mechanical conundrum afflicting my cherished 2005 Nissan 350Z, equipped with a gasoline engine, now boasting 158743 kilometers. Alas, it appears the automatic transmission torque converter lock-up clutch is exhibiting signs of terminal failure. The telltale signs are all present: the check engine light and transmission indicator light illuminating with unwelcome regularity, the gearbox slipping and shifting with the grace of a newborn giraffe, accompanied by disconcerting grinding noises during gear changes. Furthermore, the error memory is replete with evidence of this transgression. My suspicion, based on extensive diagnostics, points unequivocally to a defective automatic transmission converter. Has anyone encountered a similar automotive malady?

The conversation centers around a 2005 Nissan 350Z experiencing issues with the automatic transmission torque converter lock-up clutch, indicated by warning lights, slipping gears, and grinding noises. The problem is suspected to be a defective torque converter, which is confirmed by diagnostics. A suggested solution is to seek professional diagnosis and repair, as a faulty converter can lead to further complications. The issue was resolved by replacing the converter at a workshop.

I have a 350Z, and your description rings a bell. I experienced similar symptoms. Did you notice any engine surge, almost like a misfire, especially at steady speeds?

A most astute observation, indeed! I have noted a subtle, yet persistent, engine surge, particularly noticeable when maintaining a constant velocity on the motorway. It feels akin to a momentary lapse in the engine's resolve, a fleeting hesitation as if it were momentarily contemplating the futility of its efforts. Could this engine surge be inextricably linked to the torque converter's lamentable condition?

Likely. It's the converter struggling to lock up. I'd advise getting a professional diagnosis. A faulty converter can cause cascading problems. It’s not something you want to ignore.

I extend my sincerest gratitude for your invaluable insights and cautionary counsel. Following your recommendation, I sought the expertise of a reputable workshop, wherein the grim prognosis was confirmed: the torque converter had, indeed, succumbed to its mechanical demise. The repair, encompassing the replacement of the defective converter, amounted to a substantial 2120€. Thank you again!
