All very interesting, but also a bit puzzling: why didn't BMW put these type of fluids in our cars in the first place ? There seems to be no disadvantage, and I can't imagine that cost was an issue. Anyway, I'm seriously considering using Redline's ATF D4 or D6 when my warranty expires, as a smooth shifting gearbox adds so much to a sportscar appeal ...
