that's what i figured, i couldnt see any reason for type f to work any different in a non lock up A-518 then how it works in a 727, that's the fluid im leaning twords using the most. I will most likely use it, is there a difference between type f and type fa?



727 904 518 non puter are designed to use mercon/dextron 11 which is now dextron 111. type f in 727/518 nobody will warranty for street use,will wear out teflon seals much faster,and does not lubercate as well as dextron111, will also never work in puter controled valve body trans that reads line/valve pressure.518 with just lockup converter i can see that working, i build all my drag car trannys for years, with full manual valve bodies that shift super hard already why would you want to use type f? i only use dextron 111 in 727s. type f was designed for old iron case c-6s that robbed tons off power,so ford pulled out few cluth packs and needed more positive cluth pressure to hold trans from slipping. in bone stock trans will firm up shifts with no work done to it same as b/m trick shift. if you want a trans to bang and bark build it

i already have a transgo shift kit that will be installed shortly.
I guess i could run dexronIII if it truely has more lubricating ability then type f, but i have been told type fa has some modifyers added in it that reg type f does not, and from what i have read the type fa was made to give better lubricating ability then regular type f? all i know is my old man ran type f in his 727s and he was by far the smartest mopar guy and mechanic i have ever met.

I understand that in order to get a better performing transmission i need to look further then just changing the fluid, wich is why i purchased the transgo shift kit, i am just waiting for tax returns to pay for it to be installed, so i will have a shift kit, and i figured once the shift kit is installed thats when i'll switch to the type fa transmission fluid, that way i get the best of both worlds, a better shifting transmission because of the shift kit, and a better shifting transmission due to the more grabby type fa fluid, and i would be getting more lubricating ability and protection with the type fa, the type f and type fa are pretty much the same fluid, but from what i have learned reading up on it online the type fa does have a little bit more additives to help with its lubricating and protecting ability.

i'm sure you could order a 5 gallon pail of atf+4 from your local parts store, like napa or car quest or oreilly auto parts. in fact i seen big pails of different atf's on oreilly auto parts website.




I have been to a AZ, Napa and ADV ... none of them had a gallon or 5 gal pail available. ANYone with a specific part# ?

So, Mr.kunkel, does type fa have better lubricating ability over regular type f? i am trying to figure out what the difference is between type f and type fa, and i would assume the A in type fa means additives, and by extra additives i would assume that means it has better lubricating and protecting ability. You said dexron/mercon would be more appropriate because it has better lubricating properties so i was just wondering if the type fa would have better lubricating abilitys then the reg type f. If i do end up running dexron/merconIII what do you think of the valvoline max life dex/merc fluid? it is a full synthetic and my builder advised against synthetics, and according to the valvoline fluid tech i talked to on the phone the valvoline max life is a full synthetic universal fluid and would be fine for my transmission, that being said would i get firmer shifts with the valvoline max life or with the reg valvoline dexron/mercon fluid?

And doctor fiberglass, go to google.com and type in oreilly auto parts and there web site will pop up as a link go to it and look in there fluids and chemicals category and they are able to get drums of different atf's and oil's.

The type f fluid was designed for ford friction material which is close to early 727.I have not seen that type of friction material in 5+ years.The friction material in your overdrive housing will be new style paper linings,not the metal impregnated frictions in the forward or direct locations.If he installed a shift kit you won't get that much friction from it shifting anyway.I don't install type f in anything unless you own a old Ford.If he voids warranty because of that type of fluid i would find a different transmission builder.If you have a good external cooler any mopar fluid will be good for your transmission.My experience is to look at the transmission dipstick and fill with that fluid.

I'd use dexronIII before i would use atf+4, i have a non lock up converter so my transmission does not need the friction modifyers in +4, i am told it would make it shift real soft and run hotter, i do have a good transmission fluid cooler and plan to get a deeper delrae transmission pan that holds an extra 4 to 5 quarts of atf, i guess i'll just run dexronIII but type f or type fa is what i'd like to run, like i said i may just flip a coin, heads dexronIII tails type fa lol

I would like to know the difference between type f and type fa tho, i'm thinking the A in type fa has to mean additives, and with additives that has to mean a better add pack or more advanced add pack then regular type f, and with that being said type fa has to have more lubricating and protecting ability over regular type f correct?

Maybe you should ask the question on a FORD website ?

I think between the incoherent ramblings you got your answer.

In the end I think you know the answer but just run what you want because you obviously know more than the person that built your trans and of the most respected members of this forum .

you ask 50 dirfferent

if your hell bent on type F in mopar trans. ive seen pro rebuilers use type f and dextron111 in 50/50 mix with no harm to any older auto trans in street/strip cars.only because they had drums of it to get rid off(not big call for it in years and was dirt cheap) the street heros would have to come back to him any time they had to refill their trans with the specail secret high performance fluid it left with same as when you drop the pan for trans service/repairs and put 1/2 its fluid back to refill with b/m fluid(same as typeF)

john kunkel, you also said +4 would be fine if im not making alot of power, maybe i should have mentioned this, my engine is turning 320hp and 385 ft lbs of torque, its not a huge number of horse power and torque but its a significant amount, with the being said, is that considered enough power to worry about using a special fluid for the transmission.

I have noticed alot of people saying that the dexron/merconIII will be non excistent here pretty soon and that the only dexron there will be is dexronVI, would dexronVi be a good idea to run in my non lock up A-518? i asked my transmission builder about running dexronVi and he said oh no dont run dexronVi thats a synthetic, lhe said it like synthetic is a bad thing, kind of like oh no dont eat raw chicken that will give ya salmonella poisoning lol.
I do respect the opinions of the people on this fourm, this is just a confusing topic, some people say ya type f is an old fluid that still works great, some people say oh no type f dont have the lubricating ability and that i should run dexronIII, and some people say you should run a synthetic, see what i mean? there are so many different opinions as to what fluid you can run in this transmission that its hard to decide on wich fluid would be the best for the transmission, they all advantages and disadvantages, again it comes to wieghing the pro's and the con's to each fluid.
I am curious to know what you guys would think of trying the new dexronVi, even tho its a synthetic, (wich my builder advised against and i do not know why??) it says that dexronVi can be used in anything calling for the previous dexronIII spec. i learned today that dexronIII didnt even come out untill 1993, thats when gm introduced dexronIII, my truck is a 1991 dodge with the non lock up A-518, so factory fill in my transmission im assuming was dexronII.
Someone mentioned reading my dipstick and using what my dip stick says, my dip stick is not the factory dip stick, thew transmission shop who re-built my transmission gave me a new dip stick and dip stick tube, theu moved the tube behind the engine to get the dip stick tube away from headers and gave me a new dip stick that does not list what fluid to use, it just says check while hot and idleing in nuetral and shows me the full and low mark on the dip stick.
I dont see why dexronVi wouldnt work in my transmission, if dexronII was factory fill in my transmission, and two years later dexronIII replaces dexronIII and then dexronVi rplaces dexronIII and says its ok to use in anything calling for the older dexronIII spec. what do you guys think on the dexronVi? or if im going to go synthetic should i run the valvoline max life atf, it is also synthetic? i can still get dexron/mercon atf, but i have heard that it is not going to be around too much longer and that dexronVi is replacing it. just like +4 replaced the +3.

Exactly. There are 4 pages worth of this over at BITOG (see my link above), and who knows how many other forums. I'm not sure what he's looking for.

518's like mopar type 4, they typically do not like dextron or type f. That's how it is here in the world of mopar practical experience. Been down this road with the 518 od. OK?

You can buy real mopar type 4 in bulk from your local dealer

OK here goes...


USE DEXRON III !

Your builder said to use it, if you use anything else he may not warranty it, the different fluids do smell different. It is a decent middle of the road fluid and will not be a huge differance from the best fluid to the worst fluid. How good the tranny was built will be a much bigger factor in it's longevity.

Oh and I do put a warranty on my trannys, 12 month unlimited miles and never had to do warranty work on them and I recomend and use type-f. However if someone used +5 in it I would not deny warranty because like I said it is more about the build quality

On the subject of transmission fluid, what are the opinions on using "Universal Hydraulic Fluid"?

Several years ago, sometime mid 90's. I had a transmission cooler line fail, and literally pumped all my fluid out down the road.

I was stuck on the side of a county road, and a farmer happened by, we towed the car back to his place via tractor. And I repaired the line with some hose I kept in the emergency kit.

I now needed to get fluid in the transmission. The farmer had no transmission fluid, but did have TSC brand jugs of Universal Hydraulic Fluid.

I got the gears turning in my head, and know that some hydraulic systems uses transmission fluid, and the transmission is basically a hydraulic pump, so I added the Universal Fluid to the 727.

It worked, and worked well. In fact because I was on such a tight budget at the time, and it was my "beater" car. I never changed it back to transmission fluid.

I had the car for 4 or 5 more years, and even made a cross country road trip from Eastern Nebraska, to Western Wyoming. Never an issue or slip.

So what say the transmission builders? Was this a fluke of luck, or is there some merit to using something other than "transmission" fluid.
