GrandlandX Transmission Issues

I'm having trouble with my 2022 Vauxhall GrandlandX Hybrid. It has 229412 km. The engine management light comes on and off, and I'm getting transmission warning lights too. There are error codes about transmission oil temperature. Gear changes aren't smooth, sometimes they slip, and once in a while, the gearbox goes into emergency mode. I've even heard grinding during gear changes a couple of times. Could a bad transmission oil temperature sensor be the cause?

Sounds like it could be a dodgy tranny temp sensor. Gearbox going into limp mode is scary! Something similar happened to my old Astra, but it just wouldn't shift. Low oil can cause those symptoms too, if the sensor isn't covered. Have you checked the gearbox oil level?

Thanks for the quick reply. Can you tell me how to check the gearbox oil level on this model?

The GrandlandX Hybrid is different from my old Astra because it's automatic. I don't know the specifics, but you should take it to a workshop. It might be low oil, or the sensor itself could be bad. You don't want to mess up the transmission; repairs are very expensive. Just get it checked.

Thanks for the advice. It turned out to be a faulty transmission oil temperature sensor and slightly low gearbox oil. I had the sensor replaced and the oil topped up. The total cost was 365€.
