not necessarily, bmw used atf in their manual transmissions because they were easier to shift, its a smoother feel, bmw had a bulletin about people complaining of hard feeling shifters and the fix on the cars with MTL from the factory was to put ATF in it
Use RedLine MTlL, weve been using it since the 80s on tons of bmws and never had a problem, it does feel a little different but if the oil is old, it might make it feel smoother in some cases, also wouldnt hurt to redo all the bushings in the shifter mechanism if it feels sloppy.
EDIT:
DONT use Hypoid oil (stinky 75w90 differential/gear oil)...its been proven to eat synchros over the years
