Watching Dead Dodge Garage. Subject matter was 1964 Newport with push button Torqueflight transmission. Narrator claimed that Ford Type F transmission fluid provides crisper shifts in the torqueflight transmission than the Chrysler product. Does anyone on this board use the Type F fluid and would you recommend it? Paul
anyone use Ford Type F transmission fluid
- Thread starter spstan
- Start date
One opinion is not to use it as it breaks down at high temps. My transmission guy recommends using the latest Dextron Transmission Fluid.

I use it
When Ford came out with the Type F fluid spec, the GM and Chrysler transmissions shifted a bit quicker and crisper, as noted. Kind of like a "cheap shift kit" in a bottle. Durability has to be good as this was Ford's OEM fluid for about 20 years. Just like Dexron-family was GM's OEM fluid.
But being OEM spec does not mean the fluid is totally bulletproof! In a later version of the old BBS bulletin board Chrysler vehicle FAQs that Dr. Zatz used to run, there was a comment that Dexron III fluid started to break down at about 40k miles, but the semi-syn/full-syn ATF+4 atf would last much longer. Which also means that the current Dexron VI would also last much longer, being syn. YET the fluid change interval for "normal use" was "lifetime" or 100k miles. With severe use/heavy trailer towing use being more like 30k miles.
Lots of orientations of what fluid to use. Key thing, whatever you use, it needs to be readily available locally, should you ever need more. Default mode, Dexron III or Dex/Merc atf from a name-brand oil company.
Enjoy!

I've been using it for close to 50 years. Never had a trans failure. Good enough reason for me. It's hard to find these days but Rockauto has 3 different brands for a little over 5 bucks a qt.

I switched over to it in the 68 Fury. I will switch over in Shamu, the 69 Fury III vert, when I put a shift kit in it.

I've run it for decades without issue. One thing to remember is that crisper shifts = less clutch slip = less heat.
The late Ron Mancini, aka "Zoomo", long time Chrysler transmission engineer and drag racer, told me to use Type F for firmer shifts. It is compatible with out transmissions. The ATf+4 is a full synthetic and better, but at a cost.

Back around 1978, I was told by a Chrysler engineer that type F provided a firmer shift because there was less slippage in the clutches for drag cars and fast street cars.
So, it works good for that. For a C-body street car with a bone stock trans that's never gonna see the track, I can't see a reason to use it. The difference is minimal in that application.
It's not going to repair any problems with old transmissions though.

When operating (ie driving around) are the bands and clutch disks immersed or surrounded by the ATF oil?

I have been using type F exclusively in my Mopar transmissions. Walmart carries it and has continued to serve me well. 0 issues.

Sprawlmart still vends Type F, at about $5/qt. I used it with the 1965/66 TF w our '66 Newport for several years, along with Lucas for even more friction, got the tranny rebuilt, and stay with Castrol Transmax as per the builder's instruction. Be this as it may, if one has an older TF with some slip in the clutches, USE TYPE F!!! The builder showed me what was left of the old clutches, namely, metal discs. ALL THE CLUTCHING WAS ACCOMPLISHED BY THE FLUID! Amazing stuff that Type F.
Type F was around in the 60's yes? The late 60's, early 70's ? So why wasn't Chrysler dealers using it back then on mopar's ? Or were they?

Valvoline Type F ATF is an automatic transmission fluid that has been uniquely engineered to meet and exceed the requirements of older Ford and select import vehicles with automatic transmissions and is officially licensed and approved by Ford.
Formulated with advanced additives to prevent the major causes of transmission breakdown, it’s designed to help prevent leaks, reduce wear and tear, and maximize performance – all for much longer than conventional fluids. It has improved thermal stability for longer fluid life, better viscosity stability for consistent transmission operation, and specific frictional enhancements for smooth gear engagements.
Older automatic transmissions present their own set of challenges, which is why owners have relied on Valvoline Type F ATF for years. Valvoline Type F ATF is suitable for 1980 and earlier Ford, Lincoln and Mercury vehicles, as well as Mazda, Saab, Toyota, Volvo, and other Japanese and European transmissions that require Type F fluid. It’s specifically recommended for use in the following applications: Ford M2C33-F and M2C33-G, as well as air compressors, general purpose hydraulics and power steering systems that call for Type F.

Type F supposedly has *NO* friction modifiers.
I asked earlier if the clutch disks and bands are immersed in or surrounded by the ATF but nobody has answered that. How the ATF works in the valve body or the torque converter has got to be nothing compared to what the oil is doing at the bands or disks. And what these 727's had originally at the factory in terms of friction materials in the bands / disks - is it going to be the same after 1 or 2 or 3 rebuilds over the past 50 - 60 years?
If you have to pay attention to what modifiers are in your limited-slip / posi-track differential for it to work properly, then why is it ok to totally throw out those considerations for the fluid in the transmission?

+4 is a semi synthetic, very cost effective for when it was developed It has a solid spec best choice except for Quatrosyn
DEX III IS NO Longer regulated by GM There IS a current ALLISON SPEC everything else is built for price or ???
Although the TF is not too sensitive to viscosity DEX VI is much thinner, and cheaper, a mileage fluid TF will even work with motor oil in an emergency
Best fluid available is CITGO Quatrosyn it has NO friction modifiers to shear down and has the best low, high temp and mileage tests
Gil Younger Transgo founder and builder of our 62 Max wedge TFs said that Type F was incompatible with some seals and frictions but all those have changed in the last 60 years He said do not use Type F in anything but Ford O matic and some Power Steering units, it is a simple hydraulic fluid
