Nope.

Yeah, there is an alternative...amsoil synthetic ATF...it's $9.30 per quart, but has a 100,000 mile service life. Plus, it specifically states that it meets Hyundai specifications.

I've used SPIII & Amsoil ATF. FWIW & IMO even though I'm a bit biased, the Amsoil held up better for custumers of mine that put on mega miles.

Amsoil ATF is not compatible with Hyundai AT, whatever anybody will say, it's not.
