Ecosport Transmission Issues

Those symptoms suggest transmission problems, and the error code could help. Instead of radiator oil pressure, have you thought about a faulty transmission pressure sensor or wiring issues to the TCU? First, have you checked the transmission fluid level and condition? Low or dirty fluid can cause this. Also, check the wiring and plug connections for damage or corrosion. Why do you think it's radiator oil pressure?

I haven’t checked the transmission fluid because I thought it was the radiator oil pressure. I did a quick check of the wires and plugs, but didn't see anything. I'll check again. Can you explain how a bad sensor causes these symptoms?

A faulty transmission pressure sensor can send the wrong signals to the TCU, causing the shifting and emergency mode. The TCU needs correct pressure readings to control the transmission's hydraulic system. If the sensor is wrong, the TCU might shift wrong or go into emergency mode to prevent damage. Even if the wiring looks okay, there could be small breaks or corrosion in the connector. Given the symptoms, I'd suggest a professional diagnosis. They can find the problem. It might be a loose connector, but be careful.

I took it to a mechanic. It was a bad cable/plug connection to the transmission, like you thought. It cost 95€, which is less than I expected. Thanks for the help.
