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
Everybody else has cc already said, but the transmission fluid in particular is why it’s red.
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.
