pjc360 anyone here run the valvoline max life atf in a chrysler A-518 or 46re transmission? i have been pondering the idea of using it in my A-518, heard some good things about it.
12-13-2011 04:52 PM
pjc360 well the shop that re-built the transmission told me they put atf+3 in it, and it does shift rathly smoothly more then i'd like, he told me they would have put +4 in it but they dont like to run a synthetic untill the transmission has at least 1000 miles on it.
The owner told me to flush all the fluid out after 1000 miles and put a new filter on it, and right now my transmission has roughly 600 miles like 560 sum miles, unfortunetly i can not afford well i can afford the shift kit now, but i will not be able to afford to have it installed untill this spring when i get my income taxes back, and by then my transmission will have well over 1000 miles on it wich is when im spos to flush all the fluid out and put new fluid and filter on it.
So i was wanting to pick a fluid now and just stick with it for the rest of the transmissions life like the owner suggested, he said its better to stick with one type of fluid instead of switching around from different types of fluid.
I know the dexronVI is a gm fluid, but since the A-518 got dexronIII put in it as factory fill from 89-93 it should be safe to use because it says it can work anything that calls for dexronIII. I have just been told by old time transmission guys that type f is the best atf to run in a torque flight transmission, type f is not as updated as dexronVI therefore it would need to be changed more often then dexronVI but it supposidly firms up shifting and keeps a torque flight running cooler then any other fluid, i do not have a lock up torque converter so i do not need too many friction modifyers im told? i dont know its just a hard descsion between type f and dexronVI, i have also heard never to run a synthetic in a torque flight? my old man ran type f in all his 727s but he is no longer around to ask about running type f in the A-518 but i have heard alot of people says its ok and accually better for it then any other fluid if it does not have a lock up converter.
I will be having a shift kit installed as soon as i possibly can. I wish i could have a lab rat A-518 transmission to run different fluids thru and see what fluid it performs the best with, thats why i ask these questions hoping to find somone who has ran type f and dexronVI in the chrysler A-518 so i can ask them wich one performed better....
12-13-2011 04:05 PM
SSedan64 Personally I'd use the cheap DexIII untill after the Shift Kit & Flush was done, then use the DexVI or if you plan on regular Trans fluid changes continue with DexIII or Type-F. The Shift Kit should firm & shorten up the shifts where Type-F may not be needed.
12-13-2011 02:01 PM
pjc360 ya thats impressive compared to dexronIII, with that being said would you consider it a good fluid to run the chrysler A-518 transmission?
The canadian builder i was talking too told me that atf+3 didnt come out untill 1994-1995 and said that the main reason they came out with atf+3 was to help the clutches in the newer lock up converters when i say newer i mean 1994 and up. He said that dexronIII didnt have the heat handling ability to keep them lock up converters happy. He said prior to 1994 chrysler used dexronIII on all there transmissions even the A-500s and A-518s wich were chryslers first overdrive transmission for pick up trucks in they first introduced it in 1989 and used it untill 1993, and in 1994 is when they modified the transmissions a bit more with the electronically controlled 46re with the lock up converters that needed atf+3, he said but from 1989-1993 dodge used dexronIII for factory fill in the A-518 in diesels and gas and some gas trucks came with a lock up converter but my 1991 did not, therefore he said dexronIII would be perfectly fine for my transmission, he said all the horror stories you hear about transmissions burning up do to not running +3 or +4 never came into effect untill 1994 when they introduced the 46re wich is a bit more electronically controlled then the A-518s used from 89-93 and also has a totally different lock up converter, he said if it was a 94 or newer i would tell you to run +3 or +4 but since its the 89-93 A-518 with just the electronic overdrive and with a non lock up converter he said i have to reccomend dexronVI.
He told me that dexronVI is compatible to use in any transmission that calls for dexronIII and he said that in 1991 dodge was using dexronIII for factory fill in the A-518 transmission, he also said i could use type f if i wanted too but he feels dexronVI is a better fluid.
what do you guys think about using dexronVI? wich would be the better choice the dexronIII or dexronVI or type f? those are the 3 fluids i am trying to decide between, i know type f allows for firmer shifts and is known to handle heat better and its alot cheaper then dexronVi, but on the other hand the dexronVI can handle heat just as well if not better and it lasts longer and most likely protects better? i just wonder how it would shift with the dexronVI? i imagine it would shift a little smoother with dexronVI compared to type f but if it protects that well maybe its worth sacraficing the softer shifts? I have just been told all my life but my old man that soft smooth shifts bring heat and wear the transmission out faster then firm aggressive type shifts? I plan on getting a trans go shift kit installed in it this spring when i get my income taxes back, just trying to decide on a fluid, the transmission only has 500 miles on it and in another 500 miles the builder told me to pick a fluid and flush all the fluid out of it and change the filter and whatever fluid i decide on he told me to stick with that fluid for the rest of the transmissions life and service the filter every 25 thousand miles.
So im trying to decide on dexronIII or dexronVI or type f? wich one would be the smarter choice to make.

SSedan64 The Dex-VI is synthetic like the ATF+4, that's why it's so pricey. It's also very good fluid.

Dexron VI vs Dexron III
The following chart represents the improvements over Dexron III.
Extended Fill Range = 100,000 miles Normal Use.
Change Interval = 50,000 miles Severe Use.
Clutch Friction Stability = Improved 100%
Clutch Durability = Improved 120%
Oil Film = Increased 20%
Fluid Oxidation = Improved 100%
Shear Stability = Improved 200%
Foam / Aeration = Improved 150%

pjc360 well this finally got resolved.... the transmission shop called me back 3 days later and told me that they had to order me a new torque converter i knew there was something wrong with it, and the owner tries telling me its my rear axle making the noise and my engine missing causing the vibration??? what a joke i think they were hust trying to blame it on whatever else they could, and they told me the torque converter was bad and thats what was causing the vibration and the sounds.
I was talking to a canadian transmission builder and he told me that i should run the new dexronVI atf in my A-518 transmission? He says he puts dexronVI in the A-500 an 518s and the 47rhs and 46res whenever he re-builds any of them. Has anyone else heard of running dexronVI in these types of transmissions? he told me it has the best flow rate during low and high temps and that it has the best protecting ability? I looked at some in my local parts store and the dexronVI is kinda pricey and it also feels very thin in the bottle, you shake a bottle of dexronVI and it feels like water in there?
He said it is backwords compatible to dexronII and dexronIII and he told me that in 1991 DexronIII would have been factory fill in the A-518 transmission thats in my truck?, any thoughts on that? or would type f be a better choice then dexronVI?

pjc360 the owner of the transmission shop has still not called me back, he said late tuesday that afternoon that the next day he'd pull it up on a rack and check it out and call me back and let me know what he thinks, here it is thursday night and still have not heard from him..... I drove by there shop tonight to see if my truck was in there shop or in the parking lot and it was in the parking lot.
I'm going to call him tommarrow and see whats going on, if he is still trying to claim its not the transmission, im going to say ok put the transfer case in nuetral and put the transmission in drive and or reverse and you will hear the same whining noise im taslking about, it cant be the rear axle making the noise when its sitting at a stand still lol.
Im also going to say i brought my truck to your shop in the first place because i was told you were the best transmission shop in town, and the you backed up your work, if i was miss informed you can give me my money back for the re-build and i will take it to somone who will fix it and not give me the run around. what do you guys think? is that what i should say? because im done beating around the bush with these guys its time to be asertive now.
12-07-2011 02:06 PM
pjc360 well its 2 p.m and the owner has not called me back today so im assuming that means he has not touched it yet or he's already got it torn apart and is working on it...
If the owner calls me and says its anything but the transmission then im going to tell him that i'd like to take it to another shop and get a second opinion.

He calls me back twenty minutes later and says ya there is something going on but i think its your engine? and i said how could the engine cause the torque converter to whine? i felt like saying well i think its the transmission.
All he said was ill pull it up on a rack tommarrow and check it out and ill call you and let you know what i think is going on. i know its the transmission and nothing else and if he tries telling me its not im going to freak out, or if he tells me i have to pay for any of it im going to freak out because i paid for my re-build with cash and he gave me a 2 year warranty so they have to fix it, they messed up upon installing it so they can live with there mistake and fix it right this time.
if you have any doubts at all, pick up the truck and take it to another shop for a second opinion and, see if they say the same thing.

pjc360 well let me rant about my expierence today....
I brough my truck to the shp that re-built my transmission yesterday afternoon, the owner said he would take a look at it and call me back later in the afternoon and tell me what he thinks, well he never called yesterday....
He called me today at 1 in the afternoon and i said so whats the verdrict? he said my guys looked at it and said they couldnt find anything wrong with the transmission, i said REALLY?!?!?! I said so whats going on with it, he said the reason its vibrating in park and nuetral is cause your engine is not firing on all 8 cylinders, i said well it has brand new plugs, brand new plug wires, brand new cap and rotor i said maybe i have the firing order off but i dont think so...
I said well whats causing the wind up whining noise, he said its your rear end, i said relly? well how come when i hear it its coming from the front of the truck not the back? he said i dont know but your rear end must be getting ready to go out.
I said i really dont think soo. i just had the cover off that rear end a couple months ago and there was hardly any shavings on the magnet and there was no shavings or metal debree in the gear oil because i filtered it looking for metal debree, i said the oil looked pretty bad and old but i no metal debree in the oil and very little on the magnet, and i said i refilled it with synthetic gear oil too, did the exact same thing to the front axle popped cover off and couldnt find any metal debree in the front axles oil ether.
So after i told him that he says well i have a few minutes right now so i'll go out there and look it over real good and call you back, i said ok.
!5 minutes later he calls me back and he says im going to keep it for the night and tommarrow im going to pull it up on a rack and take a closer look, he said there is deffantly something going on but i think its your engine and whatever it is could burn up the transmission.
Let me ask this, what could possibly be going on with my engine to burn up the transmission? i think he knows there is something wrong with my transmission and is trying to blame it on the engine so that he can charge me for fixing it. The noises this is making is deffantly coming from the transmission im 99 percent sure, and none of the ever happened untill i changed the bottom transmission mounts, another thing that makes me think its the transmission. i lifted the transmisssion and transfer case up together just high enough to get the old transmission mounts out and the new mounts inn and ever since i did that is when this vibration and whine noise came about? so i have asked this before and did not get an answer, what could have happened from changing the bottom mounts on that transmission to bring about this problem? is it possible while i lifted up on the trans that it threw the converter off course? could i have damaged a shaft of some kind? or bent a bushing or threw out a bearing or what?

Bryan59EC I despise automatic trannys with a passion.
Have only had one car with an AT make it birth to death without a trans issue.

Recently (about 2 years) had the trans in my Windstar rebuilt.
Took it in to fix a random and irritating downshift to second gear from cruise.
(quite interesting to be tooling along at 70 and just have the trans drop into 2nd gear for no reason.) Did not want to shift out of second at all -- at any speed.

After the tranny guy saying it needs a total rebuild (and almost $3000) the silly van started doing the same thing within a week.

After the tranny guy had to pay for a very long tow, he then found the cause of the original problem.
Seems an expensive electrical switch was shorting out causing the car to shift into second and stay there.

He then told me his trans warrantees did not cover electrical items.
This did not go over too well with me at all----and I let him know it.

Told him I brought the car in to FIX the 2nd gear issue
Rebuild trans was at his suggestion.
I had no intention of paying an additional $400 over the cost of the rebuild to repair what I took it in for in the first place.

He bi***ed a bit about paying for the 100 mile tow and the pricey switch, but it really was not my problem.

Now about 50,000 miles later------trans being stupid again.
Cannot decide if it wants to shift into 1st or stay in second at slowdowns without stopping.
When it decides finally that it wants to be in 1st---it shifts real hard.

Just ranting here---have no constructive input at all on your issue.

(other than tossing that AT and using a manual trans )

pjc360 to be more detailed, when i walked in the door of the transmission shop the owner was on the phone and when he got off the phone he said whats up? i said that transmission is having problems of some sort, he said whats it doing? i said everytime i put it in gear and go to take off the converter is making a wind up noise or whine noise? does it all gears even reverse, and i said it is always vibrating the dash and the steering wheel and when im going down the freeway at 75 miles an hour is shking and vibrating so bad it feels like the doors are going to fall off, and he said well can you leave it with me for awhile so i can take a look at it? and i said yup and handed him the key, i said i been talking to a few people and they all seem to think that the torque converter is ether side loading or its the wrong converter or the converter was not clocked right, and he said its the right converter, and i said well i dont know all i know is the torque converter is making a ton of noise and i have a vibration.
He said i will take a look at it here in a couple hours and ill call you and let you know what i think it is, and i said ok and left. Now if he tries telling me that its not the transmission im going to laugh and say then why is the torque converter making noises whining noises? and if he says its going to cost me anything im going to say well it was my understanding that this transmission came with a 2 year warranty and my recipt says the same thing, and ill say so if you dont wanna stand by your warranty on a re-build that does not even have a thousand miles on it yet, then you can give me my money back and ill take it to somone who will fix it, this is if he gives me any crap or says i have to pay for anything? not saying he will, he may jump right on it and be more then happy to fix it for free idk im just preparing for worst case senario.
12-05-2011 08:15 PM
pjc360 well i dropped my truck off at the transmission shop this afternoon, and i explained to the owner what was going on and he said he'd take a look at it later on in the afternoon and call me back and tell me what he thinks it is.
I felt like saying well whatever it is im not paying for it cause its under warranty, he never did call me back this afternoon so im guessing he didnt have time to look at it, but when he calls me back and tells me what he thinks it is ill get back on here and let you guys know what he says.
I still need an answer to my question about running type f atf in this transmission? its a non lock up converter 2 pin connection, A-518.
I'm hoping i can run type f in it because it helps firm up shifting and its half the price that atf+4 is. thanks guys for all your words of wisdom.
12-03-2011 02:38 PM
pjc360 it can not be any of the driveshafts because the vibration is occuring at stand still as well, when i fire the truck up it starts vibrating right at start up and i can feel it pulsating thru the seat and steering wheel and the dash, its a womp womp womp womp womp just a consistent vibration that gets worse when you apply some gas to it. when you apply gas to it, ity feels like the doors are going to fall off.
Im taking it to the transmission shop who re-built the transmission on monday and im telling them to figure it out and fix it, its under a 2 year warranty and i paid in full with cash. so the least they can do is take the transmission out make sure the torque converter is clocked right and make sure its the right converter and make sure the flexplate is correct and whatever else is in there that they can check cause something is going on, im getting a whine type noise form the converter while driving, and when i crawl under it while its in park at an idle and watch the torque converter i think i can very fadly hear the same type of noise but that might just be my mind thinking im hearing that noise, but i can deffanitly hear it when i put it in gear and start to take off from a stand still.
