C30 Gearbox Slipping
Summary of the thread
A 2006 Volvo C30 is experiencing gearbox slipping and unclean shifting, potentially due to transfer case oil wear or defective gears. A suggestion was made to check the transfer case oil level and fluid state before assuming gear defects. The issue was confirmed to be defective gears, and the resolution involved a mechanic's inspection and repair.

Thanks! Did your assessment point to defective gears? How was the issue resolved on your C30?

Mine resembled defective gears, but it was complex. Get a specialized workshop to replace the oil and check the gears. If that fixes it, you're lucky.

Appreciate the insight. My mechanic inspected the transfer case and confirmed the gears were the problem, as suspected. Total cost was around 330€.

I had a similar problem with my C30, though the symptoms were slightly different. Have you checked the transfer case oil level and fluid state? Worth checking before assuming the worst.
