Avantime transmission issue

My 2003 Renault Avantime diesel, with 173241 km, is acting up. The transmission indicator and check engine lights are on. It's stuck in emergency mode, shifts badly, slips, and makes grinding noises. Error memory points to a radiator oil pressure issue, likely a defective cable or plug. Anyone seen this?

I had a similar experience with my Avantime. The symptoms sound very familiar. Was the car overheating at all, or did you notice any coolant leaks?

No overheating or leaks that I've noticed. Just the transmission going haywire and the error code. What was the fix for your Avantime's issue?

Given the symptoms and error code, it does sound like the same problem I encountered. I strongly recommend taking it to a workshop. It's likely a faulty pressure sensor or wiring issue in the cooling system circuit, but diagnosing it properly requires specialized equipment.

Thanks for the advice. Turns out it was a faulty connection as suspected. 95€ later, all sorted.
