A bit of research on the ATF +3 ATF +4 issue

Hi All,

Responding to that Amsoil poster got me into doing a bit of online research, I've compiled my findings here. Please comment and enjoy!

The ATF+3 / ATF+4 transmission fluid issue

As we all know, Chrysler vehicles with auto trannys are speced by the factory to use ATF+3 or ATF+4. Current recommendations are for ATF+4 in everything except minivans older than 1999. This normally would not be a big deal - except that over the last decade, a general consenses has been reached by everyone familiar with the Chrysler 4 speed auto tranny (known as the Ultradrive) that you have to change the fluid in it rather frequently. You can't just fill it with fluid and leave it for the life of the car. The problem here is that ATF+4 is EXPENSIVE, big time, because Chrysler has a lock on it! $8 a quart is not uncommon, and for a full Ultradrive flush you need at least a case of it. $100 for fluid alone isn't a particularly fun price to pay, espically when everyone else is buying Dexron and Type F and is paying a tenth of this.

Now, for most mid-90's vehicles, you can escape this somewhat by buying ATF+3, which isn't sole-sourced by Chrysler, and as a result is much cheaper. It's still not as cheap as Dexron, but it's nowhere near as bad as ATF+4. But, it's now been 4 years since ATF+4 was mandated, and more and more Chryslers are now needing ATF+4 for those those preventative maintainence fluid flushes.

At first glance, it seems that we can't do anything but bend over and take it in the shorts. There's pressure among fluid manufacturers on Chrysler to commence sales of ATF+4, but Chrysler hasn't given up this cash cow yet. Simply waiting out Chrysler in the hope that eventually the dam will burst isn't an option if you want your transmission to live. So, as it stands, we are screwed. Or, are we?

It turns out that there's some cracks in that dam already. This is what I have turned up in my surfing on the web.

1) ATF+3 and ATF+4 are Chrysler trademarks. Thus, ANY fluid manufacturer that uses ATF+3 on the bottle MUST get permission from Chrysler. Chrysler has a registration process for this.

For reference, in the Product Data Sheet for Chevron ATF+3 Automatic Transmission Fluid, there is the following line: "Chevron ATF+3 Automatic Transmission Fluid has been registered with the Chrysler Corporation" There is also the line "Chrysler, Mopar ATF Plus, ATF+2 and ATF+3 are registered trademarks of DaimlerChrysler"

2) ATF+3 is mineral-oil based transmission fluid. ATF+4 is synthetic oil based transmission fluid.

For reference, a Product bulletin from Gulf Lubricants for GULFPRIDE ATF +3 there is the line: "Vehicles manufactured after 1999 require ATF+4, a synthetic-based ATF only available through DaimlerChrysler"

3) ATF+3 cannot be used in transmissions requiring ATF+4, but ATF+4 can be used in transmissions designed for ATF+3.

For reference, see Chrysler's TSB 21-006-01

4) The commonly-seen claim of synthetic motor oils that they do not need to be changed as frequently also extends to transmission fluid, a claim from none other than Chrysler itself.

For reference a web link for Mopar ATF +4 sales literature contains the line: "The approved automatic transmission fluid for all vehicles factory filled with ATF+4. Check dipstick for fluid identification. A "fill for life" quality fluid."

For a second reference, a web link for sales literature for Mobile 1 Synthetic ATF contains the line "This unique, advanced technology has demonstrated extended drain"

The Chrysler TSB listed above also contains the line: "With ATF+4® fluid, color and odor are no longer indicators of fluid condition and do not support a fluid change." (ie: what do they expect that your going to use as a guideline for trans fluid change?)

Amsoil also claims this for their ATF (Need I post the actual reference, they claim this for everything)

5) At least one fluid manufacturer claims their product can "modify" standard Dexron into an ATF +4 compatible fluid.

For reference, see LubeGuard's HFM-ATF Supplement

6) Many of the fluid manufacturers claim that ATF +4 is only available from Chrysler.

For reference, see URL's from Gulfpride, Shell, and Chevron listed later in this post

7) The major oil companies are getting pissed that Chrysler isn't putting out on ATF +4

For reference, see the imakenews.com article URL at the bottom of this post

8) There are a total of THREE manufacturers that claim to be selling Synthetic Automatic transmission fluid that is compatible with ATF +4. They are:

Amsoil (duh) with it's Synthetic Automatic Transmission Fluid

Valvoline with it's MaxLife ATF

Petro-Canada with their Synthetic Blend Automatic Transmission Fluid

So, in summary, what I am concluding is that we are seeing the beginnings of a war between the oil companies and Chrysler over ATF +4, and Chrysler's attempt to squeeze it's customers. Quite obviously, Chrysler looks upon the lock on ATF +4 as a way to force people into the dealer parts departments, and as a way to gouge people for money. Yet at the same time they are not above catering to the "synthetic oil = extended drain" crowd (of which I am NOT a member) by winking and nodding that their special ATF +4 tranny fluid can last forever. I guess they are inferring that they should be allowed to gouge people because after all it's a "fill for life" Yah, right. In the meantime the oil companies are pressuring Chrysler behind the scenes, but if DC doesen't capitulate, they are getting ready to go ahead and start selling synthetic ATF and claiming that it's ATF +4 compatible. As time passes, and more and more Chrysler cars require ATF +4, the major oil companies aren't going to give up a source of aftermarket fluid revenue.

As for the idea that the synthetics (like Valvoline and Petro-Canada) that claim to be ATF +4 compatible are actually the same as Mopar ATF +4, well legally and technically, if those companies are not buying the additive package from the sole-source that Chrysler has defined, then they are not the same as Mopar ATF +4. HOWEVER, this does NOT mean that someone other than the Chrysler-blessed supplier of the ATF +4 additive package cannot come up with an additive package that is functionally equivalent. Obviously this will have to be done with a synthetic ATF. As of now, I am skeptical that anyone has yet done so, because the ATF manufacturers who ARE claiming that their synthetic ATF is compatible with ATF +4 are ALSO claiming that the same fluids are Dexron III replacements. There's plenty of ancedotal evidence that ATF +4 and Dexron III are completely different, (besides what Chrysler is saying) and it isn't logical to believe that Dexron III and Synthetic Dexron III are so vastly different as to make Synthetic Dexron III the same as ATF +4. To me, the early bird synthetic ATF producers are attempting to grab some extra money by getting a few fools to buy their fluid, who should be getting ATF +4 from Mopar.

But, sooner or later the installed base of cars that require ATF +4 will be big enough as to constitute an appreciable market, and one day one of these fluid manufacturers is going to come out with a synthetic ATF that claims compatibility ONLY with ATF +4, and NOT with Dexron III. At that time if DaimlerChrysler is still trying to hang on to their ATF +4 monopoly, it will be doing a huge disservice to the public, because people will not have any way of knowing what fluids really are equivalent. I urge people to write DaimlerChrysler and tell them to allow ATF +4 to be sold by aftermarket fluid producers such as Valvoline, Mobil and others.

REMEMBER: A TRANSMISSION FLUID IS A PRODUCT THAT IS A COMBINATION OF A BASE OIL WITH AN ADDITIVE PACKAGE. THE ADDITIVE PACKAGE IS WHAT LETS AN OIL COMPANY CALL IT ATF +4. RIGHT NOW THIS IS CONTROLLED BY CHRYSLER. NEXT TIME YOU SPEND $100 AT MOPAR FOR A CASE OF TRANNY OIL, YOU WILL KNOW WHO TO CURSE.

Not exactly...

MerconV is synthetic based. (AFAIK) I don't have current cost per quart at hand but even if it were priced at $2 a quart, dig this;

Some Ford automatic transmissions now have a drain plug in the pan (that's the good news).

Now the bad news.

The drain plug is also the fill plug.

Yup, no dipstick tube, no fill hole.

Well, we now know who's been hiring from the bottom of the engineering class.

Chrysler ain't so bad.

Ted, I cannot figure out why you're paying $8 for a quart of ATF+4. I don't pay even close to that in Canadian dollars, let alone American ones. "$8 a quart is not uncommon" -- horsepuckey! You've just apparently spent your time posting a missive about evil bad Chrysler versus oil companies instead of finding a dealer who won't wallet-rape you.

*shrug* Your choice, ace.

My dealer charges me, a walk-in consumer, a little over $5US/qt. by the quart, and something like $4.80US/qt. in gallon containers. I flushed (and will do future flushes of) my Concorde's 42LE with 16 qts. at a time, so, yeah, that's about $75 for the flush. Someone who wasn't as anal would still pay about $50 for 10 qts. I have seen enough posts on various forums to believe that there are some dealers around the U.S. that do indeed charge over $7/qt. - seems to be more prevalent in the (northern?) metropolitan areas.

So apparently if a given modern, with-it, movin'-n-shakin' manufacturer could convince you that they've come up with a true equivalent of ATF+4, you would buy it as long as they just did not tell you that it was the same stuff that was in their bottles labeled Dexron?, but just in a different package labeled for equivalency to ATF+4? 8^)

Apparently there is a factory rebate in effect for many Mopar service items, including many fluids, belts, brakes, belts, shocks, etc through the end of November. Ask your dealer to see if this applies, which could help lower the price.

Thanks, good info. However I don't use ATF +4, I have a 1995 minivan that runs fine on ATF +3. Hope this helps someone out there.

No, your missing the point. Right now the ATF +4 additive package is sole-sourced. Sooner or later if Chrysler doesen't let go of it, the rest of the oil companies are going to get tired of playing games with them, and one of them that makes additive packages is going to produce a duplicate of the ATF +4 additive package, and sell it to all the rest of the blenders. The point I am making is that when this happens they won't be able to use the ATF +4 trademark and so will create something else then that will be used by the rest of the ATF producers, which will be rather confusing for the customers.

The last thing that we need is to make transmission fluid labeling even more complicated than they are. It's bad enough that the automakers can't standardize on one fluid, but at least the ones that are out there are known by recognizable trademarks. This is only because nobody has as of yet played the games that Chrysler is playing. If all the rest of the automakers decide that what Chrysler is doing is a great way to make extra money, your going to see all of them redesign their trannys so as to take incompatible fluids.

Daniel I expected better from you. $8 is an example figure as anyone reading can plainly see. The problem is that Chrysler has a lock on ATF +4 and can set the price anywhere they choose. You cannot guarentee or even give any hope at all that a month from now Chrysler might not just decide to start charging $15 a quart.

By contrast, with Dexron, Type F and so on, because those are not sole-sourced, competition will prevent one company from gouging it's customers.

Look, I don't even own a 1997-or-later Chrysler that requires ATF +4, I own a 1995 minivan that takes ATF +3. The last time I flushed it, I used off-the-shelf Valvoline ATF+3 and it cost about $1.79 a quart. Compare that to the lowest price for ATF +4 that any respondent has posted - $5 a quart, and I paid $21.48 for a case, while your paying $60.00 And on top of that, one of my relatives that works at a Dodge dealership gave me 2 cases of ATF +4 for free that he bought for a car he owned then sold, and never ended up using. They are sitting collecting dust now.

The point is that there's a rising number of companies out there which are trying to follow the "razor/blade" marketing strategy, where they give away the item then screw you for the consumables. This has of course always existed in a small way in the auto business for many dealer-only parts like body trim, etc. But those parts are at least well within the core competency of the automakers who after all deal with parts every day.

But, getting into consumables like oil, ATF and other fluids is most definitely not in the automakers core competencies. Chrysler does not have a single oil refinery and is most definitely not an oil company. They add absolutely no value to the ATF +4 product, and by sole-sourcing it, they merely are adding more costs to the product for no reason. The fluid vendors by contrast are actually making the fluids, plus they already have an existing distribution network, adding in ATF +4 to their product lines could be done far cheaper than Chrysler doing it.

You wouldn't buy a car manufactured and sold by Exxon, why do you think it's normal to buy automatic transmission fluid from a car maker?

Anyone know the greatest mystery of all. What is the name of the company the makes the ATF for CC.

I don't have a problem with non-compatible fluids between brands, because the Tran. fluid today is so tightly tied in with the transmission design. Requiring a standardized fluid would handicap the design and innovation for the transmission fluid, and also the transmission itself. I want car makes to make improvements without waiting for the entire industry to do the same. I also expect the price of the ATF+4 fluid will fall quite a bit in the next few years as servicing of the newer transmissions becomes commonplace.

As you mentioned, Chrysler doesn't manufacture the fluids, and it probably didn't invent them either--it contracts with a specialty supplier to do that.

The fluid maker probably spent quite a bit in R&D to develop a fluid for Chrylser's transmissions that works well and lasts a long time. It may even hold some patents used in the manufacturing of the fluid. That would explain why that manufacturer gets to make all of it. As time passes, however, expect that to change, just as it has with other products.

According to a post almost exactly a year ago in this ng

,"Currently, there are only twocompanies that make ATF +4 (both marketed as Mopar fluid) which areapproved by DC: Equilon (makers of Havoline and Shell oil products inthe US) and Petro-Canada. (From what I can tell, Equilon makes +4 formost of the North American market, and PC makes it mostly for export.)"

You said it was "not uncommon". I and several others told you you're fulla shit, 'cause you are. The only logical conclusion is you're paying too much for trans fluid.

Yeah, and you can't guarantee that a month from now frogs won't develop claws and start living in toilets.

If you would kindly read the link I included in my post labeled

"Article that details Chrysler's monopoly on ATF +4"

you would see that the fluid manufacturer is being prevented by Chrysler from selling the ATF +4 additive package.

Furthermore, even if the fluid manufacturer did sell the ATF +4 additive package, the bottle can't say ATF +4 unless Chrysler gives it's permission, as ATF +4 is a registered trademark of theirs.

Let's apply the same reasoning to motor oil, gasoline, anti-freeze, chassis lube, etc.

I don't. The problem isn't the wholesale cost of ATF +4. I'm quite sure the volume of it being consumed is sufficient for whichever fluid manufacturer has the contract to make it to be able to sell it to Chrysler at the same wholesale cost that they would sell any other comparable synthetic trans fluid.

The problem is that the only distribution channel for ATF +4 is Chrysler's dealers. This dealer network and Chrysler itself add most of the cost to the fluid. Chrysler and the dealer network are designed and optimized to distributing cars, not fluids. A typical auto parts retailer is by contrast optimized for distributing stuff like trans fluid, which means they can do it cheaper, and these savings would be passed along to the consumer if there was competition.

And the interesting thing is that in the product data sheet for Petro-Canada's synthetic ATF, they claim ATF +4 compatability.

Sorry, didn't follow this thread from the start. Is the ATF-3 and the ATF-4 compatable. We have a 93 Caravan that uses the ATF3.
