XC70 Transmission AW55-50SN No Drive - Problem found... C1 frictions burned and Drum cracked

[Tone944]

I'm still procrastinating on investigating this issue, but in a moment of distraction, looking for some verification of my theory of what's wrong, and a way to assemble without damaging the seal rings, I came across a really good rebuild manual. I'll paste the link here, hopefully it will help somebody...

I'm still looking for the best way to ensure the 4-5 CLUTCH HOUSING FLUID SEALING RINGS don't get damaged on assembly and how to confirm that the bush they are supposed to contact is in the correct position

I had the same issue with a 2001 XC70. I replaced drum with a good used one and as a just reward 2nd gear was missing. I was pretty fed up and replaced the transmission with a good used one.
