I went through Amsoil Universal ATF, as well as Castrol. At that point, I went through a whole excel spreadsheet and looked up the viscosity of alot of Dex III on the market.
Anyhow, to summarize, M1 Dex III *specific* did the trick for me. When I state M1 Dex III....is because I recall seeing a universal ATF on the shelf awhile back.


Try it. If it doesn't do your fancy...that end up doing what I did was trying till it did :-)

Again..this opinion may be subjective and any Dex III will feel the same for you or sound the same...but it was quite a riot when Amsoil....being my 1st choice of lube, was too thin for the PS rack.
