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
DESCRIPTION
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.
NOTE:
CAUTION:
• 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-
TURES.
• 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.
