Eon transmission control issue

My 2016 Hyundai Eon with the gasoline engine has 116k km. Lately, the gears have been acting up. The paddle shifters don't work at all, and the gearbox feels like it's slipping sometimes. I'm hearing some grinding noises when it shifts. The paddles are super slow to respond when they do work, and the car went into emergency mode the other day. I scanned it, and there's an error stored. Anyone else had similar problems? I'm thinking it might be something with the transmission control.

Sounds like a transmission control unit issue. The symptoms you describe, especially the error code and emergency mode, point in that direction. Have you checked the wiring harness for any damage or corrosion? That can sometimes cause similar problems.

Thanks for the quick reply! I haven't checked the wiring harness yet, but I will. Where exactly should I be looking for it? And is there anything specific I should look for besides corrosion?

The wiring harness runs to the transmission control unit, usually located near the gearbox itself. Look for any obvious signs of damage – cuts, frayed wires, or connectors that aren't properly seated. Given all the symptoms, I still suspect the control unit itself is faulty. You should take it to a workshop, they have the diagnostic tools to check the error codes and test the transmission control unit to confirm.

Thanks! I appreciate the advice. Took it to a shop and you were spot on. They ran diagnostics and confirmed the transmission control unit was defective. Cost me 1000€ for the repair, but it's running smoothly again.
