Kadjar transmission fault

I'm having issues with my 2022 Renault Kadjar diesel. It's got 152,849 km on the clock. The engine warning light keeps popping up, and sometimes the transmission warning light as well. Error codes point to a faulty transmission oil temperature sensor. The gearbox occasionally goes into emergency mode, and I've noticed some slipping and unclean shifts, along with a grinding noise when changing gears. I've researched, and a potential cause could be low gearbox oil. Has anyone experienced something similar, and if so, what steps did you take to diagnose and fix it?

Sounds familiar. I had similar overheating problems with my Kadjar. Is the gear shifting especially rough when the engine is hot?

Yes, exactly! The rough shifting and grinding noises are much more noticeable after the engine has been running for a while and things heat up. When it's cold, it's not as bad. Did replacing the temperature sensor solve the issue for you, or was there more to it?

In my case, the low gearbox oil level was the culprit. The sensor was just reporting the symptom. I'd recommend getting it checked at a workshop.

Thanks a lot for the advice! I took it to the workshop, and you were spot on. Turns out the gearbox oil level was indeed low. They topped it up and replaced the faulty temperature sensor while they were at it. The total repair cost came to 365€. Now it runs like a charm again! Appreciate the help!
