Actually, that lack of red dye seems to be one of the trademarks of a lot of
the "SP-III" fluid sold. SP-III is the recommended replacement for a lot of
Hyundai and Kia vehicles. In fact, of all of this type of fluid, none that
I have seen or purchased is nearly as red as most of the other brands
(Dexron, ATF+3, F, etc.).
That does NOT mean it isn't as good a fluid. But it does make it harder to
see when it is getting time to replace it.
