Arkana transmission error

That sounds rough. Something similar happened to my Arkana last year. First, check the coolant level; if it's low, there might be a leak messing with the pressure readings. Also, check the cooling fan. If it's not working, the system can overheat and trigger those sensors. Did you notice any car overheating?

I checked the coolant, and it seemed fine. No car overheating either. The cooling fan seems to be working. Where did you have a leak, and how did you find it? Was the pressure gauge faulty or something else?

Mine wasn't a straightforward leak; it was a tiny crack in a hose that only leaked when the engine was hot and under pressure. It was impossible to spot at first. After messing around, I took it to a workshop. They pressure tested it and found it quickly. Considering the error codes, especially the transmission stuff, I'd get it checked professionally to be safe.

I appreciate the insight. I booked it in, and you were spot on; it was a corroded connector on the radiator pressure sensor. 95€ later, and it's running perfectly.

The Renault Arkana car is showing a red warning light with the message "transmission cooling temporary stop". What should be done?

First, ensure your vehicle is parked safely and turn off the engine to allow it to cool down. Check the transmission fluid level and condition; low or dirty fluid can cause overheating. If the fluid level is low, top it up with the recommended type. If the issue persists, or if the fluid appears burnt or contaminated, have a professional mechanic inspect the transmission system. Let me know how it goes or if you have any further questions.
