D4 is not bad either. I have had really good experiences with AMSOIL gear fluids, and I know a lot of people that will not use anything else.
Mobil 1 gets the nod for being a great product with easy availability and better price competition.
^This. Toss up between Amsoil's ATF and Redline's D4. M1 would be an 'easy' choice if in a pinch and availability of the other two are a concern.
I haven't had experience with Royal Purple's universal ATF product yet, but it should be higher-end quality though compared to the others I don't know where it would rank on my 'list' of favs?
