Caravan Automatic Transmission Problems

Having transmission issues with my 2023 Nissan Caravan (gasoline engine). 208,000 km on it. The automatic transmission is shifting weird, transmission light keeps popping on, and sometimes it feels like it's not shifting at all! It even went into emergency mode a couple of times. Could it be the transmission oil?

A 2023 Nissan Caravan with 208,000 km is experiencing automatic transmission issues, including erratic shifting, a persistent transmission light, and emergency mode activation. The problem may be linked to undervoltage affecting the transmission control unit, potentially caused by a faulty battery or alternator. Checking and replacing the battery resolved the issue, restoring normal transmission function.

Sounds familiar. I had similar transmission problems with my Caravan. Is the shifting rough, like hitting a wall between gears? Does it feel like you're driving through mud sometimes? It might be undervoltage in the vehicle. Have you checked the battery and alternator?

Yeah, that's a pretty good description! Rough, like hitting a wall... exactly! Undervoltage, huh? I hadn't thought of that. How did you figure that out? And what did you do to fix it?

I had the same symptoms, and eventually the mechanic told me it was undervoltage messing with the transmission control unit. It's like the computer brain controlling the shifting was getting scrambled signals. I'd recommend getting it checked out at a workshop. It cost me around 240€ to get sorted, but it fixed the problem completely.

Thanks a lot for the advice! I really appreciate it. I'll get the battery and alternator checked ASAP, and if that doesn't solve it, I'll take it to a workshop and mention the undervoltage issue. Hopefully, it's a simple fix. Turns out it was the undervoltage after all! New battery and all is well.
