Jeff-
My buddy builds transmissions for a living. He's been doing it for almost 25 years now, and he tells me that the BMW tranny oil is 125/gallon. I doubt the price above that your MB parts guy gave you is incorrect, but I'm curious to know if the 18 liters it calls for is the TOTAL capacity, or if you're going to lose 18 literes by simply removing the tranny pan. I highly doubt it, but I don't know enough to comment.
There was a time that generic transmission fluid was what they called dex/merc II or III, but now transmission fluid has gotten pretty fancy. The ZF-5 speed in my one ton calls for Mercron V, which is a synthetic fluid itself. It's also a ridiculous 5.00/quart. I don't want to say that Mercron V is the way to go, but if you wanted a synthetic, there it is at Wally world.
As many have said on the thread- if they're running Dextron III and having no problems, that's what I'd run with. I plan on doing a filter and gasket swap this weekend if I have time.
