Are there any good replacements for the ATF M-V auto trans fluid specified for a 2004 Mazda 6S ?
From Mazda Service Bulletin 05-005/08, dated 4/11/2008
Always be sure to use the correct automatic transmission fluid when replacing ATF. Using the wrong ATF may cause shift quality complaints or may even damage the transmission.
• ATF M-V (TYPE M5) IS NOT THE SAME FLUID AS MERCON®V ATF.
• ATF M-V (TYPE M5) HAS A GREATER VISCOSITY THAN MERCON®V ATF IN LOW TEMPERA-
• ATF M-V (TYPE M5) HAS A GREATER ANTI-JUDDER SPECIFICATION THAN MERCON®V ATF.
• USING ATF OTHER THAN ATF M-V (TYPE M5) IN AUTOMATIC TRANSMISSIONS DESIGNED TO USE ATF M-V (TYPE M5) MAY CAUSE SHIFT QUALITY COMPLAINTS.
• USING ATF OTHER THAN MERCON®V IN AUTOMATIC TRANSMISSIONS DESIGNED TO USE MERCON®V MAY CAUSE TRANSMISSION DAMAGE.
I would ask at the Mazda parts counter for any SB more recent.
I, for one, would not experiment with any other ATF fluids.
My brother’s 2010 Mazda also uses M-V atf
when servicing the transmission, I just wound up getting the atf from the Mazda dealer. The price per quart was quite reasonable, if I recall correctly. In fact, it wasn’t more expensive than aftermarket multi-application atf, might have even been cheaper.
