GX transmission warning lights

I have a 2023 Lexus GX Hybrid. Getting engine and transmission warning lights. Error memory shows a transmission oil pressure sensor fault. Gearbox slips, shifts roughly, and sometimes makes a grinding noise. Seems to go into emergency mode sometimes. Mileage is 46632 km. Any ideas?

Oh, that sounds frustrating! I've got a GX too and had a similar issue last year. Check your gearbox oil level first. Seriously, it could be something simple.

Where exactly is the gearbox oil level check? Never done that before, and don't want to mess anything up.

Well, I'm no expert, but in my case, low oil was definitely the culprit. But I still suggest you bring it to a workshop, or at least check a video tutorial. You don't want to mess with the transmission.

Thanks! Turns out the gearbox oil was indeed low. Topped it off, and the warning lights are gone. Shifts smoothly now. Cost me 365€ for a full oil change and sensor check.
