SM3 transmission oil temperature sensor issue

My 2013 Renault SM3 with a gasoline engine is giving me headaches. The transmission oil temperature sensor seems faulty. The engine warning light is on, and there's an error code related to the transmission. It goes into emergency mode sometimes, shifts are jerky and occasionally I hear grinding noises. Gearbox oil level is ok. Any ideas?

I had similar issues with my SM3. Is it an automatic? Check your gearbox sensor; maybe it's faulty as well. Start with the cheapest repairs you can find.

Yes, mine is automatic. Was it the same symptoms? Did you also experience the emergency mode and the grinding noises?

Exactly the same symptoms. At the time I changed oil and sensor. The problem was gone, but I made a mistake, and didn't do it myself. The sensor replacement itself isn't that expensive, but the car needs to go to the workshop anyway to read out the error memory.

Thanks for confirming! I'll check the sensor first. Already scheduled a visit at my mechanic to change the sensor. The bill will be around 365€. Hopefully, that fixes it!
