Yeah 6 sided socket (make sure it is in mm), soak in PB Blaster, and then use a breaker bar (extension tube). And I don't want to scare you or anything but I have experienced better performance, and longer life with normal dino tranny fluid and diff fluid than synthetic stuff, don't know why doesn't really make sense to me, all I know is I have heard of more tranny's burning out after synthetic switch, and more issues in diff's after going to synthetic than those who stay with the normal (recommended stuff). Maybe it is due to not getting level correct or maybe it is due to synthetic leaking more, I am not sure, but that has just been my experience with the VX and making observations from who is having what problems on here. Just a little 2 cents, and know I will be sticking with the cheaper (recommended) fluids, except on the engine, always have gone synthetic there ;-)
