Valvoline Maxlife Multi Vehicle ATF doesn't carry
ANY manufacturer approvals/certifications. They say it basically works with everything besides ATF+4 & Type F (Or extended drain Allison TES-295)
ZF would never approve a multi vehicle ATF, Valvoline does have a GM approved Dexron VI ATF
HERE .......It's not Maxlife MV ATF!
Not that Maxlife MV ATF is a bad fluid......Been using it at my shop for Dexron III/VI & Mercon V/SP/LV applications with great results! Don't really like it for Honda DW-1 spec units though.....Genuine DW-1 works better in my opinion. My daughters 2009 Civic with upgraded Raybestos GPZ frictions really didn't like Maxlife at all, Shifts like butter with genuine fluid.
Haven't tried it in a ZF 8HP yet, But works great on Ford 6R80 (ZF 6HP) units.
More relevant information on the ZF 8HP......I subscribe to this magazine (Tech publication)
