How Do Univ. ATF's Meet Many Specs.?

[Whitewolf]

The fact is that many do not 'meet the specs'. Most commonly the wording will be 'suitable' or 'recommended', not very often APPROVED. Qute simply if a given fluid does not even meet the basic viscosity requirements for a given application (which is common) then by that definition alone it does not meet the specification.

The Japanese based all their ATF specs on Dex-II/III and added their own requirements to it. The Germans(Daimler, ZF and Voith) haven't said which they used for their base ATF spec. The JASO does have a published spec(M315). ZF and Voith test fluids - but only in heavy truck/bus applications or older passenger car specs.
