Galloper gearbox slipping grinding error

Hi, I have a 2002 Hyundai Galloper, diesel engine, with 177069 km on the clock. The gearbox is acting up. Shifting isn't possible using the paddle shifters, the gearbox slips sometimes, and I hear grinding when it shifts. The paddles are slow to respond, and sometimes it goes into emergency mode. Error code is stored. Could it be the transmission control unit?

The 2002 Hyundai Galloper is experiencing gearbox issues, including slipping, grinding, and slow paddle shifter response, sometimes entering emergency mode with an error code stored. These symptoms suggest a potential problem with the transmission control unit. It is recommended to have a professional diagnosis, as the issue may require specialized tools and expertise for repair or replacement.

Hello there. Your symptoms do sound like a defective transmission control unit, yes. I had similar issues with my old BMW 5 series, although the grinding wasn't present in my case. The emergency mode and error codes are very telling. Was the issue always present or did it begin gradually?

It started gradually, yeah. Anything I can check myself before taking it in?

I understand. Unfortunately, with electronic control units, there isn't much you can do without specialized diagnostic tools. Given the symptoms you described, especially the emergency mode and stored error code, I would strongly recommend taking it to a trusted workshop for professional diagnosis. A defective control unit often requires specialized programming or replacement, something best left to experienced technicians.

Thanks for the advice. Took it to a shop and they confirmed it was the transmission control unit. Cost me 1000€ to replace but it's running smooth now.
