First, please realize that you will be far from doing a transmission "flush." Second, changing the fluid isn't exactly a simple drain and fill. There is a proper procedure that must be followed, the transmission must be cycled properly and in a specific manner, the fluid must be at the proper temperature throughout the process, etc. You certainly don't want to overfill or underfill.
Now as far as fluids are concerned, the -807 fluid is Esso LT71141. If I were going to do such a transmission job (and I personally wouldn't) I would most definitely use the same stuff that BMW used and only that fluid. So my suggestion is get yourself 9.5 quarts of this fluid and not monkey around for a buck savings here or there. Also get the OE filters and not some aftermarket or other OEM stuff that costs a few bucks less.
If you don't want to purchase the fluid from BMW in the 20 liter drum for $616.48 retail ($30.82 per liter) then I suggest you contact these guys (see post #1) and find out what price they give you:

Or order it from a place like Bavarian Auto:
Welcome to bavauto.com | Automatic Transmission Fluid - ESSO LT71141 - 1 Liter
Or shop around yourself for the best price and post your result. As far as Redline fluids or any other brand are concerned, I personally stay away from them. Could they be better, sure, but they could also be worse and given the other option is using OE fluid which I know is what the transmission manufacturer spec'd for that gearbox I would feel more comfortable using a product that the manufacturer knows works well. Good luck.

But I have one follow-up question - I did a Google search on the VW/Audi fluid, and got a link from Redline which claimed that their D4 ATF meets or exceeds the specs of the other two fluids. I did a search on Redline D4 on this forum, and nothing came up. What are the opinions of this ATF? It's considerably cheaper than the VW/Audi fluid (about $10 a liter vs. about $15), but of course if there's any doubt, I'd gladly spend the extra five bucks a liter for the peace of mind. My X5 has 78,000 miles, by the way, and isn't exhibiting any transmission issues; I'm just interested in doing a tranmission flush as preventative maintenance. Thanks.
