I think over the years they have done enough analysis to determine which fluids last longer then previously thought or the newer fluids perform better.

Why would BMW state lifetime and not state say 130,000km to change the transmission fluid? It would be in their best interest to have you back at the dealership in 130,000km. So who, knows really.

I will change at 130,000km also.
