Hello,

I noticed that a July TSB now calls for a new ATF Fluid in the 2011 Azera called SP4-M and that the old SPF- IV is now not recommended. Anyone know why and whether or not you should do a drain and fill with the new fluid as a preventative measure?

Also, any approved or products that meet the SP4-M specs made by any other company other than that labeled by Hyundai?

I'm buying a used 2011 Azera and just want to avoid issues.

Thanks
