V50 2.4i Auto transmission flush/fluid?

[LarryUSA]

My 2005 V50 2.4i auto (I'm in the US) is going in for it's 127.5k service tomorrow. Previously they recommended a transmission fluid flush/replace but reading up, it seems this is a sealed unit and doesn't need replacing? If I can get away with it I would prefer not to at $223 to do it. Also looked at the official Volvo service schedule and it doesn't mention it at all?

Today they quoted $440 to do this! I declined, and that's at an independent!
