Lexus NX transmission fault

I'm experiencing a worrying issue with my 2016 Lexus NX gasoline. The mileage is 37194 km. The engine warning light is on, and the error memory indicates a transmission oil pressure sensor fault. Furthermore, the gearbox is in emergency mode. I've also noticed some gearbox slipping, unclean shifts, and even grinding noises when shifting gears. Can someone help me with this?

That sounds familiar. I encountered a similar problem with my 2014 Opel Insignia. The error was also caused by a faulty transmission oil pressure sensor. Have you checked the transmission oil level? A low oil level could be the culprit.

Thank you. I hadn't considered that. Do you think the low oil level could actually cause the sensor to fail, or is it more likely that the sensor itself is defective and causing the error?

In my case with the Insignia, the low oil level caused the sensor to send faulty readings, triggering the error. While a defective sensor is possible, checking the oil level is the easier first step. If the level is fine after that, then you probably need to visit a workshop.

Thank you very much for your help! I took your advice and had the transmission oil level checked. It turned out to be the issue! After topping it off and replacing the pressure sensor, the problem is now resolved. The repair cost me 365€. Your suggestion saved me a lot of unnecessary troubleshooting.
