I've been reading some mixed answers around the internet but there's no clear answer. Mazda says this is a "lifetime fluid", so the transmission is sealed.
Various forums say that you can change the fluid, but some places aren't willing to touch sealed transmission units (including the dealership themselves). This answer also applies to those ZF units which could introduce various problems if you mess with those sealed units.
Anyone have any experience with transmission fluid drain and fill on a SKYACTIV Mazda?
