Seat Altea Transmission Problems

I'm pulling my hair out here! My 2005 Seat Altea with a gasoline engine is giving me grief. The engine warning light keeps popping up, and sometimes the transmission warning light as well. I've got an error stored, and the gearbox keeps going into emergency mode. Plus, it feels like it's slipping or shifting really rough, and sometimes I even hear grinding noises when shifting gears. Could this be a transmission sensor issue?

I had similar transmission issues with my Altea. The symptoms you describe point toward a faulty gearbox sensor. Have you checked the transmission fluid level? Low fluid can cause those problems.

Fluid level? Where do I even check that? And is the gearbox sensor the same as the transmission sensor?

Yes, gearbox sensor and transmission sensor are the same thing. Checking the fluid level yourself can be tricky depending on your mechanical skill. Given the emergency mode and grinding noises, it is best to take it to a workshop. They can properly diagnose the transmission issues.

Thanks for the help! I took it to the workshop, and it was the transmission sensor. They also said the gearbox oil level was low, which probably caused the sensor to fail. Cost me 365€ for the transmission repair!
