Clio automatic transmission converter issue

I also have a Clio, and this sounds like something I dealt with not long ago. Did you feel any unusual vibrations, especially at lower speeds or when accelerating? Also, have you had the transmission fluid checked recently? It could be more than just the converter, but that's a good place to start.

Thanks. I haven't felt any vibrations beyond the usual. The transmission fluid was checked about 20000 km ago during a routine service. Is there something specific about the fluid I should know?

Since the fluid check wasn't recent, it's worth checking again to rule that out. But with those error codes and shifting issues, it does sound like the torque converter. Given my similar experience, I'd advise getting it checked at a workshop. Be ready for a potentially big bill.

Thanks for confirming my suspicions and sharing your experience. I took it to a workshop, and they confirmed the automatic transmission converter is defective. The repair is estimated at 2120€. I appreciate the help.
