Wow what a complicated web manufacturers can weave for us when it comes to trying to figure out what transmission you've got! As far as I know, the only automobile manufacturer that actually "makes" their own transmissions are GM, Ford and some Chrysler units. All other manufacturers pretty much source them out to Aisin-Warner, Jatco, ZF, etc.. Long story short, the Santa Fe and Sonata apparently use a derivative of the Mitsubishi F4A51, that is also shared with the Dodge Stratus, Mitsubishi Galant and Eclispe. To further twist things, Mitsubishi really never 'made' their own transmissions as far as I know and sourced them from Jatco. So in essence, the F4A51 is really a Jatco derivative as far as I can tell. Anyone know this to be different? BTW, I'm at 40500mi on this trans and I'm sure it's never been drained/filled. I'm REALLY temped to use "suitable for use where SP-III is spec'd" Valvoline Maxlife ATF, but I may use dealer SP-III if they are not ridiculously marked up on price. I'm still covered by the remainder of the Hyundai B/B 5/60 warranty.
