Super Tech Mercon V in Nissan Sentra 2.5L 4AT

[HJC]

Do you guys see any problems with using the Super Tech Mercon V? Manual says Nissan Matic-D or Dexron III. Car is 2003 Nissan Sentra SE-R 4AT. 65,000 miles. Dealership did an ATF flush at ~30,000 as recommended by manual.

The ST MV bottle says compatible with DexIII, DexVI, Matic-J.. and a bunch of others. Says on the back that this is a synthetic blend ATF.

This is for a car that currently sees about 5-7K miles per year. Since it's so cheap, I plan a drain and fill once a year.

I'd like to know also since I have an 04 Altima with the 2.5 and a 4 speed auto tranny which calls for Matic-D.

The ST Mercon V also claims to work in Hondas which call for Honda Z-1 ATF. I'm tempted to try it next time since it's a synthetic blend and the Z-1 is a dino (which cost over $8 a quart and is a marginal fluid IMO). I'd give it a try.

Mercon V is backward compatible with Dexron III and also a step up. I use Mercon V in my GM cars and my BMW

"Compatible" means it will work but, most probably not the best. I would stick with a "Recommended Fluid"

Just use the ST Dex VI. That is what I'm using in my infiniti now.

Matic-J is backwards compatible with the older spec of Matic-D your Nissan calls for. That being the case, Walmart Supertech Mercon V will work fine in your trans. When in doubt, any Dexron III works perfectly in Nissan Matic-D applications.

Use the MerconV. Other options are the import, highmileage, and universal or multivehicle ATFs. No need to use matic-d in Nissans.

Not so. Before I used it I called the manufacter and spoke to a tech represetative. I was told that for liabilty they can't so to use Merc V in place of Dexron III, but it meets and exeeds all Dex III specs and is a better replacement anywhere that Dex III was origianly used

DONOT run DexVI on your Nissan Tranny, it will slip. Just went thro that exercise. I have run MerconV in my maxima tranny and it held up very good. Since the price of MerconV and Castrol Import MV ATF is not significant, I would settle with Castrol since it held up the best in my tranny.

Beware, DexVI won't cut it in your tranny, it will slip.

Supertech Dexron VI (via drain and cooler line flush) did not make my 13 year old Nissan / Jatco slip, it shifted well with Dexron VI. But after about 5,000 miles of use it began to whine when fully warmed up. I concluded that the viscosity had dropped too low (Dexron VI starts low) and sure enough, a simple D&F with a regular viscosity ATF subdued the whine. I would use Mercon V rather than Dexron VI in a Nissan / Jatco transmission of the matic-D era.

Thanks for all the input. I bought some ST Merc V to the drain and fill. If the lines are easy to get to, I may even do a flush. I'll keep you guys updated if anything happens.

Obviously your tranny had issues because I've been using DexVI and I've never had any slip. You can't say DON'T run DexVI because you had issues. There is nothing wrong with Dex VI and I actually did a drain & fill in my mother's 96 Maxima GLE with 230k...no slip!

interesting...nothing like that with my car. I just plan on doing a drain & fill with ST Dex VI every 10 or 15k.

When I drained my pan which had 10K on DexVI it came out like red wine and not ATF. It was super thin, I was amazed how thin the fluid looked. Over the years of drain/fill, this was the thinnest fluid that I ever saw coming out of my vehicle(s) trannies the visocity was way too low to even call it ATF.

IMO Castrol Import MV AFT is best bang for the buck for a Nissan tranny that is out of warranty.

Odd...but doesn't all Dex VI starts off a little thin?

 

[NightRiderQ45]

Also MaximaGuy...I found one of your old post from late Oct. about ST DexVI and you said that you didn't have any issues with the fluid in 13k; so how all of the sudden your tranny was slipping in 10K??

All ATF fluids "suck" once they hit the 15K mark. Having said that, I would use ST with OCIs.


Another one of your post that conflicts with the 10k you listed while your tranny was slipping.

Nothing, I mean nothing holds up beyond 20K, u can take my word on it. Almost all miles are highway and to be honest I don't drive it like a 60yr old, I drive it well for what it is designed for (though I never abuse it with WOT etc).

I have 170K on it and the reason it has lasted this long is becoz the fluid has been exchanged frequently.

All ATFs worked the same on my tranny, the best results were Castrol Import ATF, all others including M1 suck when they hit 15-20K miles, period.

True, with a drain/fill with 4Q removed the tranny work predictably.

I did another drain and fill with DexVI it started to slip at around 10K miles subsequent to the change. In and around half way thro the tranny started to act up, I had changed my revoln sensor and thought that may have been the problem, but when I got all of the DexVI out, the tranny settled down and the shift points were predicable.

So essentially the fluid with 2 drains/fills was getting thiner.

In short DevVI is NOT a solution for Nissan trannies. Period.

Seems to me and others that you are just plain confused and your recommendations/advide should never be taken seriously.

I also had issues with Dextron VI in a Toyota transmission. Had a acceleration delay with the old T-IV fluid and a thump in a Toyota Sienna trans. Flushed originally with T-IV and thump was still there and then tried several other fluids and Supertech Dextron VI made the tranny slip. Best performance with Supertech Mercon V. Transmission seemed to settle down on that. Dextron VI is backwards compatible per GM for GM applications only. Walmart claims on their bottles that both of these fluids are compatible with T-IV but I can tell you they don't perform the same. Wear probably was a factor in my case and the Mercon V worked better. Also I remeber a post a while back (from Canada)about Dextron VI and someone posted a picture of the back of a bottle of Dextron VI that says it is not compatible with T-IV fluid so there are some contradictions out there.
