Bought pennzoil says dex/merc on it.For use in vehicles previously servicable by dexron-lll & mercon brands.This is going in 727 trans with 3500 stall newly rebuilt.Did mopar used to use dexron lll.Hope this is the right stuff.
 
All the big trans shops use Dex in everything.
A lot of people including myself use Type F, and there are a lot of opinions on the subject but when it comes down to it ANY transmission fluid works just fine and has for decades.

Now watch, somebody is going to tell you I'm wrong and that they ONLY use Brad Penn or Royal purple or some other 10 dollar a quart oil.
 
Your wrong...I only use Walmart brand of ATF....lol
 
Use should use this! No Kidding!

If you can not find the Mopar brand then the Walmart brand is just fine!

And much cheaper!

It's probably not still sitting there anyway, wherever that is.

Actually I took that pic at Garlits a couple years ago as a vendor was selling them! Loved it and had to capture! I always use type F in 727's. Firmer shifts and less clutch wear!

Good morning everyone.

Here is the lowdown on transmission fluids:

Automatic Drive Fluid. Used on REALLY REALLY REALLY early automatic drives.
Automatic Transmission Fluid, Type A: Used for a few years in the '50s
by everyone until:
Automatic Transmission Fluid, Type-A/Suffix-A. This
stuff is also called AQ-ATF. Specified for Torqueflites until:
DEXRON came on the scene in the late '60s. Dexron was the specified
fluid for Torqueflites until:
DEXRON II replaced Dexron in the 70s. There were some early-90s variants
of Dexron II called Dexron II-D and Dexron II-E. Dexron II was specced for
Torqueflites until VERY recently, when:
DEXRON III shipped in place of Dexron II. Dexron III fluid also meets
"MERCON" specs for Furds. Dexron III is specced for new Torqueflites,
but not for some of the new FWD MoPars, notably the Neon, which call for
ChryCo Spec 7176 fluid.

NOTE: Type "F" Fluid replaced Type "A" as the recommended fluid in
Ford's automatic transmissions, instead of Dexron. "racer myth"
abounds as to use of type "F" in a Dexron transmission to get firm
shifts. But I'm not about to try this on an expensive Torqueflite
transmission which shifts beautifully on new Dexron III. I cannot
recommend this procedure. Stick with what Chrysler says here.

There was also a Type "JD" fluid in the '70s for Furds with "Jatco"
automatic transmissions, but I believe this too has been superseded by
Dexron II and III.

HERE'S THE IMPORTANT PART:

The A/AQ-ATF/Dexron fluids are BACKWARDS-COMPATIBLE. That means that all
transmissions that called for Type-A, AQ-ATF, Dexron, Dexron II, Dexron
II-d, Dexron II-e, or Dexron III should now be using Dexron III.

LubriPlate still markets Type-A/Suffix-A fluid. There is no reason to
use it in your Torqueflite, since you get better shifting, less wear, and
much longer fluid life with the newest Dexron. Old clutches in good
condition have no problem with new Dexron. My father's '62 Dodge Lancer
just had its second drink of Dexron. First time was at 20,500 miles with
Dexron II and a new Fram P1651PL original-type in-line trans filter.
Shifted fine until 59,*** miles when it started popping into Neutral at a
stop light when cold. So, we got a new in-line trans fluid filter and
had the trans fluid changed, bands adjusted and a mild shift kit
installed. The shop used Dexron III, and it works well.

Ralph, I suggest you go ahead and change the fluid and filter (!) and
adjust the bands and cables as per shop manual specs. Also, you'd
probably like the kind of shift kit we now have in both our
Torqueflites. It's not the big, hairy B&M item, rather it's a TransCo.
It makes for a lot less wear on the trans because it eliminates bindup
between 2 and 3. And the trans just feels precise without being harsh.

Then why would Mopar sell this type "F" I posted?
Seems a bit contradictory! I know what I have witnessed and my tranny was last rebuilt in 85. It sat for many years but worked hard prior to that " Drag Racing" and still does today. I also run it in my Power Wagon for 20 years and she shifts firm and great! I only recommend this fluid, maybe wrongly but it is not a myth!
 
Type F has, or DID have, Sperm Whale oil as an important component, because it had advantages, like resisting heat breakdown, and it does shift a bit firmer, so it must modify friction.
Upper cylinder lubricating systems sold in the 60s also called for "top oil",
which contained whale oil.
I don't know if anything or what is used today to make type F have the same properties, it's likely just whatever DEX is, and simply labeled as F.
If Marvel Mystery Oil still uses whale oil, I would be shocked.
Nothing has to "be" what it's actually labeled anymore.
You can find "Merthiolate" on the shelf in a pharmacy, but it's not the red-orange mercury based antiseptic that really works, it's just benzalkonium chloride, like "Bactine".
Kaopectate , named for Kaolin and Pectin, now contains neither ingredient, it's just the same stuff that's in Pepto-Bismol.
And made in America is one of a pack of various lies that usually means someone in the US added a sticker proclaiming that, and calls that a step in "manufacturing" the item.
 
There was a county Sheriff's Dept in California in the early 60s that specified before they purchased county cars from a manufacturer that the transmission and engine had to use the same oil. Chrysler stepped up to the plate and they ended up using 10w30 in the engines and Torqueflites. All worked just fine.

It's verifiable online. I had the link to the article, but I don't know what happened to it.

Like I always said, "TF's would work just fine on filtered recycled French fry oil"

Not calling BS, but would you put 10W30 in your torquefight? I do not have the kohanas to attempt it! Could be costly! Tranny fluid no matter the type is much thinner!

So what your saying is California has always been F up?
 
I am actually usisn 303 hyd fluid from tractor supply, 30 for 5 gallons! Seems fine so far.

I just went through this two weeks ago, I ended up being more confused leaving the the store than when I walked in. I put dex merc, in my 727 and it works great. Dex Merc replaced the old Dextron III, type F works too but may make It shift a little more firm.
 
ATF is nothing more than Universal Tractor Fluid with additives. My trans builder,(TSR Racing transmissions) recommends Type F for Torqueflites with modern bands and clutches. The bands and clutch and seal materials are far superior today than 50 years ago. If you have an OE torqueflite by all means use Dexron , but, modern updated TF's should use "F"
 
Two tea bags boiled in 2 gallons of distilled water with 1/4 cup of olive oil, your tranny will never be the same....
