SM3 Transmission Fault

Guys, I'm pulling my hair out here. My 2014 Renault SM3, gasoline engine, is throwing a fit. Getting the engine light, sometimes a transmission warning. I'm feeling some serious slippage and rough shifting, plus this awful grinding noise occasionally when I shift. Error memory says transmission oil pressure sensor fault. Could it be just low on oil? It's got 241946 km on the clock. Anyone else seen this?

Transmission issues on an SM3? Sounds familiar. I had something similar happen, though not exactly those noises. Is it consistently doing it, or is it intermittent? Have you checked the basics, like the oil level? Before you panic and think it's the sensor itself, eliminate the easy stuff.

So, you had similar symptoms on your SM3? Was it definitely the oil level? Or was it the sensor itself in the end? How much did it cost you? Any details would be appreciated!

Okay, so with those noises, it wasn't JUST the low oil like mine initially was. Mine just had the rough shifting. With the grinding, I'd say you're past the 'add oil and hope' stage. Honestly, get it to a workshop ASAP. I ended up paying 365€ for them to sort it all out, including a new sensor. Could be worse, right?

Thanks for the advice! Workshop it is. Sounds like I'm in for a similar bill. Appreciate the help!
