Lubrizol Multi-Vehicle ATF Additives

[Johnny]

Well, while the two of you are going at it, it appears the one to answer the question would be Lubrizol since they are the one that makes this additive package. And I would venture to say that they know their business pretty well. I'm sure they did thorough testing before they released this information.

And I actually gave you a little credit for thinking outside the box. That paper, my friend, does NOT prove a superior fluid cannot or has not been designed.

Listen, as tough as you try to make it, ATF is not a giant mystery. GM, and other OEM's need a low cost, decent fluid. Other companies make better ATF's. No need to let that bother you so much.

And so on that we shall agree to disagree ... I'm at the far opposite opinion to you, let's just leave it at that.

Happy Thanksgiving all.

Key Industry Drivers and Trends

There is significant activity in automatic transmission fluid (ATF) development, mostly driven by a desire for increased fuel economy and consumer driving comfort. OEMs and dedicated transmission builders continue to modify the transmission hardware to deliver improved efficiency; therefore, requiring changes in the PTF for optimum performance. Much of this activity is in the area of six-speed automatic transmissions and, primarily in Japan, continuously variable transmissions (CVTs) for the popular compact car segment. In Europe an emerging focus is on double-clutch automated manual transmissions.

OEMs continue to state their desire for fluids that are essentially fill-for-life. For passenger car OEMs, further fuel economy improvements must be balanced against existing gains in fluid durability. Heavy-duty OEMs continue to push for increases in drain intervals to minimize maintenance requirements.

As the technical challenges for these transmission types increase, the fluids required to provide optimized performance are becoming increasingly specific both to the hardware and to the individual transmission builder. This trend toward more specific fluids and market fragmentation will continue through the decade as new transmission designs come to market along with their translation into the service fill market. Multiple products will then need to be available that meet each unique set of requirements.

I just wanna know one thing, does whitewolf and The Critic sleep with this infamous SAE paper under there pillows at night? Whatever makes you feel better guys!

In the future perhaps Buster. Not quite yet.

This has been such an ongoing debate between the advocates of both sides.

How specific does an OEM fluid need to be, before a universal fluid will not work? Looking at various drivers out there with positive experiences using multi-vehical formulation in supposedly very specific transmissions, the answer may seem to be rather simple.

If Honda transmissions can ONLY take ATF-Z1, then why does Amsoil ATF seem to work well in it? Many users have reported very subtle differences in shift quality, and these guys are perhaps the very, very observant lot. Perhaps 99% of the general public can't tell the difference between an ATF-Z1 filled transmission and an Amsoil ATF filled one.

Which leads me to think, that the absolute fluid property, may not be so critical after all. If the fluid falls within a reasonable range, then a transmission will work fairly well with it. If you stuck 80W90 gear oil into a Honda auto transmission, I am very sure you will notice very quickly it doesn't work, because the fluid properties are VERY different.

Just my 2 cents.

Well, the reality of it is as time goes engine builders are making the fluid more specific to their particular transmissions and materials they use. Most one size fits all or universal products are generally not the best at any one category, but rather a jack of all trades which is what Whitewolf was saying. I don't think it's a problem in most transmissions, yet, as many do have success with M-ATF's, but this does not mean the original fluid was not idea. As Infineum said above, this is the trend.
