SC Gearbox Slipping

I had similar gear grinding in my old Saab after neglecting the gearbox oil changes. Maybe check for transfer case oil leakage first?

Thank you. Did the Saab exhibit similar gearbox slipping, and was the root cause confirmed as oil-related?

Yep, exact same symptoms. Turned out the oil was way past it. I'd get it checked by a workshop; they'll know better than I do.

I appreciate the confirmation. The diagnosis confirmed the issue, and the repair, including new oil, was 330€. All seems fine now.
