I understand BMW claims "lifetime fluid"; and I see on the net various supposedly bad-luck voodoo stories where the transmission fails (just because) just after a replacement of the fluids.

Can someone edify me as to WHEN we should consider replacing the lifetime fluid?
Riskant, in this thread serviced his tranny at ZF Industries - Dortmund. In post #11 he posted that ZF recommends to change the ATF at 100,000 - 120,000 Kms max (60-75 k miles). That's right from the horses mouth.
