Got a non lock up A-518 and am trying to decide wich atf to run, i wanted to run atf+4 originally but the guy who re-built my transmission told me that atf+4 has alot of friction modifyers that my transmission does not need because i have no converter clutch. I have always been told that type f is the best atf to run in a torque flight, my old man ran type f in the 727 in his 70 plymouth cuda 440-6 pak car and in his 77 dodge truck and had great results, he always told me that you want a firm shift not a sloppy shift. I realize the A-518 has an overdrive unit so it is not exactly the same as a 727 but they are very simliar, is there any reason type f would perform any different in a non lock up A-518 as it does in the 727? I was considering the valvoline max life atf, but the owner of the transmission shop who re-built my transmission told me to stay away from synthetics and type f, in fact he said anyone who runs type f in a torque flight is an idiot... wich i had to strongly disagree, my old man ran type f in them and he was the smartest mopar guy i knew, unfortunetly he has passed away so i can not ask him bout running type f in the non lock up A-518. The owner of the transmission shop told me to run ether dexronIII or atf+3 or a non synthetic universal fluid, wich is what i think they put in my transmission. So what fluid do i use? i have a good sized transmission fluid cooler mounted on outside of my raditor and i plan on getting a transgo shift kit installed, with that being said should i run dexronIII, type f. or valvoline max life even tho max life is a synthetic and my builder told me not to use a synthetic atf? i dont know why he said no to synthetics he didnt explain himself on that he just said no synthetics no type f no +4 and said if you can still find +3 you can use that, if not put a non synthetic universal fluid in it or dexronIII and call it good. He told me to flush all the fluid out and change the filter and fill up with new fluid after 1000 miles, i am currently at 600 sum miles, so its coming up and i need to pick a fluid to run, thanks

Type F lacks the lubricating properties needed for the overdrive. Dexron/Mercon would be appropriate for a non-lockup 518.

I have always ran type-f in my re-built trannys for my self and customers and have not had one come back. I do always drill holes for extra lube to the OD mabey that is why or mabey I am lucky I probably just do one t-flite a month, Mr, Kunkle on the other hand I think does a lot more I am always willing to learn a little something...

the problem with the synthetics and +4 is they are all desighned with lots of friction modifiers, those modifiers make the clutches slip when they engage. Slipping clutches makes for softer shifts so the manufactures are useing it to make softer shifts because softer shifts sell cars. On the other hand slipping clutches also mean burning clutches especially at elevated power levals. Type-F has the highest friction and helps the clutches grab faster and slip less. It is somewhat of a trade off because the pistons, gears, bearings and valves will see less wear from higher friction. In my experiance the best trade off is to make the clutches last longer and increase lube to mechanical stuff through minor mods in the fluid flow circuits.

Most of the bad overdrives I have seen it was bad clutches not hard parts although I have seen one of the big roller bearings in the back go bad and one set of planataries go bad in one. I run type-f in my personal stuff and tow with the OD all the time Dexron III is close but not quite as slippery as mopar +4. Either way you choose I don't think it is a huge differance, I just like giving mine the extra little edge and yes, you can feel the differance in going from +4 to type-F while dexron III will be in the middle.

do not run royal purple or redline there synthetics are too slipery for puter trans, if you can find +3 from a dodge dealer that would be the best, if not cheapest +4. if you run dextron III you must use with +4 additive also found at dodge dealer.

I have ran it in one non-lock-up 518 (non a lot of them out there)and it was behind a very serious SB stroker and that was like 6 years ago and it is still working fine. I run it in my 97 46RE (electronic 518) and it is fine.

Here's the difference, the planetaries in the 727 are only running in the first two gears and can survive without much lube. The 518 planetaries are running almost constantly and need better lubrication.
Those who are sucessfully running type F in OD transmissions illustrate the old adage..."There's a difference between doing it right and doing it wrong and getting away with it".
As stated earlier ATF+4 is formulated for lockup converter clutches, not needed in a non-lockup 518 but it won't do any harm if you're not making tons of power.

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 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# ?

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

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.

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.
THX for the effort .. but there are no OAP's in this area.

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.

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.
