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?
I like the CASTROL MERC V... Max Life Im sure is good but it a multi vehicle ATF...
Read specs of Castrol V.. I like how its CERTIFED and APPROVED by FORD.. MAX LIFE is not it just says suitable for Mercron V... Not even recommended.. just suitable.
I would really go with Castrol.. read the specs and info and you will do the right thing.
