Avantime transmission issue

I'm experiencing a transmission issue with my 2003 Renault Avantime (gasoline engine). The car has 121818 km. Paddle shifters are unresponsive, gear changes are rough and slipping, and I'm hearing grinding noises during shifts. The gearbox seems to be in emergency mode, and an error code related to the transmission control unit is stored. Could this be a defective control unit?

Sounds familiar. I had similar symptoms on my Avantime. Are the paddle shifters completely dead, or are they just slow to react? When it happened to me the transmission diagnosis revealed a faulty control module.

They are completely dead. The display doesn't react when I use them, and the car stays in whatever gear it was in. Did you also experience the emergency mode?

Yes, emergency mode was definitely part of it. Given your description, it really does sound like the transmission control unit is the culprit. To be absolutely sure, you should let the error memory be read out. If that confirms it, there is probably no way around going to the workshop.

Thanks for confirming. I suspected as much. I will take it to a workshop and have the transmission control unit checked. I expect repair costs of around 1000€.
