Standing in Wally's tonight waiting for my tires to be put on, I was reading the backs of the ATF containers, since I'm changing the ATF on my 1999 Buick LeSabre shortly.
All the bottles marked "Multi-Vehicle Formula" said they were suitable replacements for Dex-III, and to be used in any unit that called for Dex-III, and not to use in any unit that called for Dex-VI.
I've heard that GM made Dex-VI the recommended ATF for all their units that formerly specified Dex-III. Doesn't that make all those Dex-III-compatible fluids superfluous, since GM changed the spec on all their transmissions to Dex-VI?
