From going through this myself and from what I have read here, MB uses vacuum a little differently. It is used more to smooth the shift along with the modulator. The reason is the modulator is adjusted for a certain pump pressure then vacuum is applied, depending on the IP linkage position, to smooth the shift. Try this link to help explain:
