The instructions in that "service manual" won't get anywhere near all of the fluid drained. Joe_Black has a good tranny fluid change HOWTO on his website. The procedure is fairly easy, and it's well worth the effort. I switched over to AMSOIL ATF a couple months ago and I couldn't be happier.
Would anyone happen to have some good instructions on how to change the filter?
