01 accent tranny fluid question

im changing the filter and fluid and i had one parts place tell me i needed hyundai brand transmission fluid. then i had another place tell me i could use castrol multi import vehicle transmission fluid. i understand that the hyundai is what is intended to be used. i guess my question is will the castrol stuff work?

Old post, but for anyone else browsing.

Any transmission oil meeting the SP-II m spec's. Castrol has the multi import synthetic that meets this.
