Vauxhall Adam gearbox slipping

Interesting. I've seen similar issues with the Adam. It's like when you're running low on engine oil – things just don't move as smoothly. Have you checked the oil? What did you find? Any gear grinding noises?

The oil level seemed normal, but I haven't drained it to check for metal shavings. Gear grinding is present, yes. What was the cause in your case?

Ah, that's a key point. My problem turned out to be defective gears in the transfer case. Considering your symptoms and the grinding, I'd strongly suggest taking it to a workshop to get it properly diagnosed. Don't delay too long; the repair costs tend to escalate if you keep driving it.

Thanks for the advice. Took it to the shop as you suggested. Defective gears, just like you said. Repair cost was 330€. Appreciate your help!
