I have been told by a few mechanics and automatic transmission builders that swepco atf is a really tough ATF, it can take severe beatings and still not oxidise and it also has a very stout add pack in it that makes it very close to the original dx iii H formulation.

I have never tried it myself (online stuff) but if you read about it - you wont find anything negative.

OTOH - if you want a good ATF then the NAPA one or even the regular valvoline dex/merc is a good choice - you need to change both at 25000 miles anyway.
