ATF-2, DEX/MERC, DEX VI. E4OD

I have an abundance of BMW fluid that is labeled ATF-2. Now I Cannot find anymore details on this so im wondering if its known rather or not this can be used in an E4OD. I also have DEX/MERC and DEX VI. Ive read a thousand forums with contradictory things and I just don't trust them. I'm just looking for a clear and definitive answer and what should be used. Thank you all for your time.

Re: ATF-2, DEX/MERC, DEX VI. E4OD

I have never tested it, but I suspect that the BMW fluid will kill the E4OD. I know that Dexron VI will kill it. DEX/MERC is fine, that is what it was designed to use. MERCON V is also good. Anything else is death.

Re: ATF-2, DEX/MERC, DEX VI. E4OD

Both MERCON and MERCON V are synthetic if you buy synthetic, and non synthetic if you buy non synthetic.

That fluid is probably fine. If they are still producing it to meet the now obsolete MERCON standard it's fine. If they changed it, maybe not. Who knows?
