Bingo!

You definitely understand the problem. Which fluid we recommend depends on which transmission we have.

However, maybe there are only 3 "major" types of E39 transmissions? Am I correct that there are only three major types of transmissions in the E39 with respect to fluid needs (i.e., yellow sticker, green sticker, and black sticker)?

I realize out of these THREE E39 transmission sticker types there are zillions of transmission models within those three types - but I'm hoping it's as simple as choosing the fluid for a particular transmission based on the color of the sticker on the bottom of the transmission itself (mine is green, for example, so I'd use the fluids specified for a green-stickered transmission).

To make matters worse, people specify a fluid by brand but not by model, so, for example, MTL could be Redline MTL or Maxima MTL; so I'm trying to write the recommendations specifically, including all the relevant information.

BTW, I think I understand the transmission data well enough to fill in what folks left out.
Are these assumptions correct below?
- yadayadayada has a 6-speed manual & uses Royal Purple Synchromax synthetic MTF (so he has a yellow-sticker transmission)
- chiefwej also has the 6-speed manual & uses Royal Purple Synchromax synthetic MTF (he also has a yellow-sticker transmission)
- edjack uses "MTL" which is probably Redline MTL (but it could be Maxima MTL) so he must have a manual transmission also (yellow sticker)
- Graham uses Mobil1 in his "slushbox", so he has an automatic transmision (green or black sticker); yet Mobil1 Synthetic ATF is certified Esso LT 71141 so Graham probably has the black-sticker transmission which expects Exxon LT 71141 certification

These are assumptions, but I'll bet I'm right (tell me if I'm not).
