2003 XC90 (5-cyl) transmission fluid choices?

[2003XC90]

Thanks for all of the posts regarding how to change the transmission fluid on the XC90 (inline 5 cylinder)! I read that you need either the very expensive Volvo fluid P/N 116 1540-8, Toyota T-IV, or Mobil ATF 3309, which is a bit cheaper.

I use Amsoil synthetic gear and motor oils for most of our vehicles, and have been using their latest ATF (http://www.amsoil.com/storefront/atf.aspx). The technical specs lists that it's suitable for JWS-3309 applications. Since I alread have a couple of cases of this Amsoil ATF, I'd like to use it.

Has anyone used this Amsoil ATF or can confirm it's suitable for our vehicle? Thanks!
