After spending about 2 hours reading a lot of threads on transmission fluid, I'm getting confused now...

I want to change it on my car (1991 300CE, engine 104.980, transmission 722.359) because it has 108k on it and I'm not sure when it was done last time (I've got it for 2 years now). The transmission is working fine (knocking wood...).

Could someone tell me:

- what MB recommend for that transmission (Febi?),

- what users have good experience with?

- is Mobil 1 ATF synth OK?

Thanks,
