Matiz automatic transmission fault

Afternoon. My 2004 Chevrolet Matiz (gasoline engine) is showing some troubling signs. Mileage is at 229085 km. The transmission indicator and check engine lights are both on. The automatic transmission seems stuck in emergency mode, shifts aren't smooth, and I'm hearing grinding noises. The error memory shows a radiator oil pressure defect. Could a defective cable or plug connection really be the culprit?

A 2004 Chevrolet Matiz is experiencing automatic transmission issues, indicated by warning lights and rough shifting, with a grinding noise. The error memory suggests a radiator oil pressure defect, possibly due to a defective cable or plug connection. A similar issue was resolved by replacing a faulty pressure sensor, which was confirmed by a mechanic, leading to smooth operation after repair.

Hmm, sounds familiar. I've got a Matiz too. Was the gearbox slipping/shifting uncleanly? Mine did that when the pressure sensor went bad. Did you check the pressure gauge?

Slipping and unclean shifting, yes. Where exactly is the pressure gauge located? Is it difficult to access?

Okay, so it's probably the same issue then. I wouldn't know exactly where it is now, but I remember that it wasn't too difficult to change. I would recommend to go to the workshop, though.

Thanks for the advice! I had the cable and plug connection checked at the shop, and you were right. The mechanic found the sensor faulty. 95€ later and it's running smoothly again.
