OK,

I have searched and done my home work.
ATF M-V is not Mercon V per Mazda Bulletin (see attached file).

What is everyone using as an alternative ATF fluid?

?Redline D4ATF
?Mobil 1 ATF
? Other brands

Any long-term results?

Whomever wrote that PDF is on glue.

Page one says ATF M-V (Type M5) is not the same as Mercon® V

Page two specifies REQUIRED SERVICE FLUID: ATF M-V (Type M5)

awesome.

So much for shift quality complaints when not using TypeM5 fluid :rolleyes:

I have Mercon V and it seems to have less shift shock then before I swapped the fluid.Maybe the thicker viscosity is what causes that.
Im gonna get a bottle of Lubeguard and put it in ,maybe 2. Ill let yall know if it helps any.

I used Castrol Import Multi-Vehicle Automatic Transmission Fluid that meets both Mercon V and Toyota T-IV standards.

I don't have any shift shock issues. Once in awhile when cornering aggressively it will select a much lower gear and lurch a little bit (from like 5th or 6th to 2nd or 3rd) but I drove a CPO Lexus ES330 and it was MUCH worse so I don't really worry about it.

Lubegard is highly regarded stuff. I've never heard anybody complain about it's performance except for those that expect a "repair in a bottle" and nothing was going to make them happy anyway.

I've put Lubeguard in my ATX, along with a cooler and several drain-refills using Redline D4, have made my trans. shift pretty smooth. ( And i have the Jatco)

I've had the Mercon V Lubegard in for a few weeks now,and can say that it does "feel" different. As advertised it helps with TQ converter lock-up shudder. I used to get slight shudder in 4th around 2K rpm.Now it's pretty much non-existent.
Shift shock is alot better,but I still get it. Though not as bad ,but mainly on colder days. But you can't really expect a fluid to fix shitty transmission shift programming.....

The tranny does feel like it puts down slightly more of the power to the ground. Which it does say on the package helps to reduce clutch slippage.
If nothing else, if it extends fluid and transmission life like it says .I'd say it's well worth the $16 I paid for it.

I would recommend Lubegard to anyone from my experience thus far.

want more info,hit up : www.Lubegard.com

Couple things:

1. I noticed that Valvoline Synthetic Mercon V is red (I think they added the red dye to the ATF).
Can you mix Valvoline Synthetic Mercon V with existing factory Mazda MV without problems?

2. Also anyone can point me to a DIY to disconnect cooler line for a complete ATF Flush?

Thanks!

in my opinion, i think its a long delayed post to have a sticky post on alternative M-V ATF fluid recommendations.
i feel mazda's M-V fluid isn't really good stuff as it degrades fast, and the colour turns brownish-black very easily.

please think about it.

cheers!

Royal Purple does not list Mazda M-V under their compatibility. Redline does not list Mazda M-V either.

Amsoil
Mobil1
Schaeffers
Valvoline Maxlife
Those are the only ones who list Mazda M-V compatibility on their sites and product sheets that I have found.

is this the valvoline ATF you're referring to?

MaxLife® DEX/MERC ATF


if i'm not mistaken, i believe quite a number in this forum has used redline D4 on their 5speed, and it has no issues. redline detailed product info depicts that their D4 is suitable for use in replacement of mercon V fluid.

The 6i is the 2.3L 4cyl model; the 6s is the 3.0L V6.

Both models were available with a 5-speed manual or an ATX. Depending on the model year, the 6i auto was 4 or 5 speed; the 6s auto was 5 or 6 speed.

aah, i see.
pardon my ignorance, cos in singapore, the late model mazda 6 released here has the 2.0l and 2.3l both equipped with the same 5 speed box. early models of the 2.0l had 4 speed.

Ugh, again, Mazda M-V is NOT MerconV. It is Mazda5, Mazda-V or M-V spec. It is its own specification. The FNR5 5spd ATX found in the 2006+ 6i DOES NOT USE MERCONV. Even when the FNR5 is used in Fords, it does not allow the use of MerconV. There is a TSB from Mazda specifically addressing this issue because they are not compatible.
