Mercedes C Klasse Hybrid Transmission Problems

Sounds familiar I have a C Klasse as well and I had similar symptoms a while back check engine light rough shifting and even some engine surge at certain speeds The error code also pointed to the lock-up clutch in the automatic transmission Did you notice if it happens more at a specific speed or when the engine is under a heavier load

Yeah the engine surge is definitely there As for the speed it seems more noticeable around 80-100 km/h especially when going uphill or accelerating to overtake Did you end up replacing the entire converter or was there another fix

Unfortunately replacing the whole converter was the only reliable solution in my case Given the symptoms and the error code it's likely the lock-up clutch inside the converter is failing Prolonged driving like that could cause further damage to the transmission I'd suggest getting a second opinion from a reputable workshop but prepare for the worst

Thanks for the insight I took it to another shop as you suggested and they confirmed the converter fault I had it replaced and it shifts like new now I appreciate the help
