Completely wrong KingCrab.
I researched various ATF's over the past month while trying to pick the best choice for vehicles. Amsoil ATF came up well recommended and with a stout add pack for an ATF. They offer multiple viscosities, including a low visc Fuel Effic ATF (5.9 vis). If you want a fully stout DEX 3 they have that in both in both the regular MV ATF and Torque Drive selections (7.6 vis). For manual transmissions requiring ATF those 2 Amsoil choices rank near the top.
There are Amsoil VOA's on this site as I searched for them over the past few weeks. Google "Amsoil ATF VOA" and they should pop up. I also ran across MaxLife ATF, RL ATF D4, Mobil 1 synthetic ATF. There's a thread on here from 2009 that shows 3 of these VOA's: RL, M1, and GM MTL/ATF (link below). I think you'll find that the add packs for M1, RL, RP, and Amsoil ATF are fairly similar, and stouter than your generic brands of ATF. Even Honda ATF DW1 and Valvoline MaxLife come up much stouter add packs than the generic Dex3/Mercs. My only concern on MaxLife was the lower visc of 6.0 since I was looking at ATF for a manual trans.
Fwiw this is what I ran across:
Amsoil ATF used oil analysis at 50K miles: visc 6.6, Bo-220 ppm, Ca-220-300, Phos-400-550,Zn-20-130
Amsoil ATF TD VOA - visc 7.6, VI 180, Brookfield 8410, Ca-28, Bo-133, Phos-230.
I found a fairly wide range of results based on VOA's and used oil analysis I ran across, so I put them down as a range. In one sample Zn was 20, yet in another was 130. There's also the issue of reformulations from older samples taken to newer products. Of course these VOA's leave out important stuff like FM's and other additives. Cost-wise, I'd just got with Mobil 1 ATF if I was looking for an automatic trans synthetic.
