Transmission failure from high idle?

I just heard a story about MB transmissions failing while sitting in park or neutral and idling at higher rpm - 2500 or so. The examples I heard were during high-idle emssions testing (pre smog dyno) in CA, and when people would rev thier engines while jumpstarting another car. According to the story, some MB transmissions maintain elevated internal pressure when revved up, even when in park or neutral, and the pressure causes pump failure.

Is there any truth to this one?
