Fortuner Gearbox Slipping Grinding

My 2009 Toyota Fortuner (gasoline engine, 186120 km) has the engine light on and a stored error. The gearbox is in emergency mode, slipping, shifting poorly, and grinding during gear changes. I suspect the transmission oil pressure sensor. Could low gearbox oil cause all this?

I had a similar experience with my Toyota Fortuner. Your symptoms sound familiar. Did you check the oil level? Low oil can cause these issues by affecting transmission pressure.

Thanks, I appreciate hearing about your experience. Can you give me more specifics? Did the low oil directly relate to the sensor fault and the symptoms you saw?

Yes, low oil was the main problem for me. I first thought it was the pressure switch, but adding oil fixed it. Since you mentioned grinding, get it checked by a workshop to rule out mechanical damage. I paid 365€ to have mine checked and refilled.

Thanks for the help and sharing your experience. I'll get it inspected at a workshop. It sounds like low oil and maybe sensor issues need expert attention. Hopefully, my bill will be similar.
