S80 Torque Converter Issues

Alright, I'm officially stumped. My 2011 Volvo S80 diesel is throwing me curveballs. 175k km on the clock. The check engine light and transmission indicator lights are both on, and the gearbox is slipping like crazy, especially on shifts. I'm even hearing some grinding noises now and then. Pulled the codes, and it's pointing towards a defective torque converter lock-up clutch. Anyone else run into this nightmare?

Sounds rough. I had something similar happen on my S80 (petrol, though). The slipping and grinding sounds familiar. Did you notice any performance drop before this all started? It could point to converter failure.

Yeah, definitely a performance drop. Feels sluggish, especially uphill. If it was the torque converter on your S80, what was the damage? Was that definitely the issue?

Sounds like the converter, alright. Yes, the garage confirmed it was the torque converter. You should get it properly diagnosed, though, just to be sure. But the symptoms match pretty closely. I ended up having to get mine replaced. Just go to the workshop and ask them for a quote.

Thanks! Taking it to a shop next week. Looks like it’s going to be expensive - they are estimating 2120€ for the repair, but at least I have a better idea of what I’m looking at. Cheers for your help!
