That’s really surprising, and I don’t think it is typical.
I’ve taken several cars over 200,000. A couple have hit 300,000. Right now, today, the v70XC has 300,000. The XC90 has 248,000. The 2002 V70T5 has 220,000. All of them bought used.
Not one transmission failure. Not one.
No judder. No poor shifting. Automatic transmissions last about forever, in my experience.
To be fair, three of them, the 2001-2002 Volvos, got valve body work early in their lives. That early intervention precluded later problems. The 2000-2002 AW-55 transmission was known for valve body issues. But intervention, with the transmission still in the car, is not a “failure”. The frictions and all the rest of internals were untouched.
