ATF M-III, M-V, or equivalent (e.g. Dexron II) . This is what my owners manual states to use. I would like to know if the M-III and the M-V mean mercon3 and mercon 5 or does it mean a different type of fluid and would anyone here recommend the Dexron II fluid. I really don't like to put GM stuff in my car. Thanks in advance for the input.
