I'm at 88K miles on my green label A5S 325Z automatic transmission; I've updated the glovebox printout with the replacement interval (plus everything else said in this thread) and I edited the transmission-specific summary in post 1 of this thread to 60K miles (averaging your recommendations).

Unfortunately (for me), nobody suggested a replacement fluid other than what the Bentleys listed (BMW, Texaco ETL 8072B, or Shell LA2634) and I haven't yet found a total volume (I could assume "about" 10 quarts to buy but that doesn't tell me how much to put in).

Even after all this, for my specific transmission (2002 525i automatic), I still have the two basic questions unanswered:
Q1: Are the 30K/60K/100K suggestions above for both the manual and the automatic (or would they have different intervals)?
and ...
Q2: Does ANYONE have any other suggested replacement fluid (green label "A5S 325Z" transmission)?
Q3: Does anyone have a volume for the "A5S 325Z" transmission?
I am old-school, so I like doing the old-school maintenance.

I like to replace the transmission fluid every 20k-30k miles, regardless of an automatic or manual transmission.

Since you are at 88k miles, it still might be considered risky replacing the ATF IMO, as is other people's opinions as well.

However, I replaced my ATF and filter at 80k miles, and again at 90k miles.
I think I remember reading a thread from "Riskant" about having his ZF transmission serviced at ZF, and that ZF recommended replacing/ servicing the ATF/ transmission every 60k or 80k, not sure which... (I can't remember...)

It depends on you, what ATF you want to use.
OEM or something else.
Again, if you want OEM, the OEM ATF part number should be on the bottom of your transmission pan, or, just call the dealer, give them your VIN, and they should be able to give you the OEM ATF and a price with a part number.

Or, you try Mobil 1, Castrol, Amsoil, or Redline.
I believe all of these are compatible with your ATF/ transmission.
However, knowing you.... I would gather that you will probably go with the OEM ATF (Pentosin) to play it safe.

Look here for info and quantity:

According to the charts...
You have a ZF tranny 5hp19.
Takes 8.9L with and 6.2L without torque converter.

~6 quarts is what I took out and put back in...
