Not that fancy, same transmission is used by like 10-20 different marques including Mopar products (literally the same transmission is used in Jeeps, RAM trucks and Rolls-Royce) But I know the fluid from my rusty 19 year old Audi which has the old 6 speed but came with updated software that requires the newer fluid from the 8 speed.
But I must say, it’s an excellent fluid. 400k km on the original fluid and filter before it started giving trouble at -30C (fixed by the fluid and filter change). And this transmission is actually more mechanically complex and finicky than the newer 8 speed ones so imagine how long those might last if someone decides to replace the fluid at ZF’s suggested interval rather than BMW or Audi’s “lifetime” spec lol
Lifeguard Fluid 8 is blue or green, I forgot which exactly but definitely not red.
This would more likely be coolant, though I’m not sure what colour coolant modern BMWs use
Fair enough. I’ve checked levels on a good number of transmissions over the years but never a fancy BMW’s. Possibly also power steering fluid.
