So with my past Volvos, especially my 2004 V70R, I would change the ATF fluid every 50k. I can't recall if the manual claimed it was a lifetime fluid or not. But I did fluid changes anyway, pumping it out through the ATF hoses at the radiator.
With these new SPA cars and advanced AW transmissions, are they designed such that they really rely on a lifetime fluid, i.e. the transmission depends on all the suspended particles that will accumulate in the fluid since it's never changed? If so, I will certainly abide by the lifetime change interval. If not, I will go with my gut and change every 50-60k or so.
