S Klasse transmission issues

Sounds familiar I had something similar happen with my S Klasse too The implausible shifting and emergency mode are no fun at all For me it turned out to be undervoltage messing with the car transmission's brain The system gets all sorts of confused when the voltage drops Have you checked your battery recently That might be a good place to start before you assume its a full blown transmission oil issue Think of it like your computer acting weird when the power is low

Undervoltage you say That's interesting I hadn't considered that angle So if the battery is weak it could cause these kinds of automatic transmission problems Even with the transmission oil being old Tell me did your transmission indicator light come on as well And were the symptoms exactly the same

Yep the transmission indicator was on and the shifting was all over the place It felt like the car was constantly second guessing itself like a bad chess player Old transmission oil definitely doesn't help but the undervoltage can cause all sorts of electronic gremlins with the automatic transmission I'd still recommend getting it checked out by a professional to be sure They can test the battery and see if it's sending the right signals to your car's computer

Thank you so much for sharing your experience It's incredibly reassuring to know I'm not alone in this and that there might be a simpler explanation than a complete car transmission overhaul I took your advice and had the car checked It turned out you were spot on It was indeed a case of undervoltage causing the issues with the automatic transmission They replaced the battery and did a transmission oil replacement for 240€ and now my S Klasse is shifting smoothly again I really appreciate your help
