I've got an '89 Lincoln Town Car and want to change the ATF fluid and filter soon. It has the Ford AOD transmission. I was going to use either Motorcraft Mercon V or Valvoline Maxlife, but I found some discussion at a different forum that stated Mercon V fluids were not good for the clutches. This could have been the original formula of Mercon V, which may have been updated, or maybe it was just not factual. I haven't seen or heard any other reference to this. Has anyone here had issues using either Mercon V or Maxlife in a Ford AOD application?
