Why Transmission Fluid Is Not Lifetime
BMW once labelled the ZF 8HP and 7DCT as having lifetime fluid — this claim has since been revised. In Malaysia's heat, ATF and DCT fluid break down faster than in Europe. Dark fluid at 20,000 km indicates oxidation and reduced lubrication. A X7 gearbox rebuild costs ; a fluid service costs . At 4M Car Care we check transmission fluid condition at every major service.
