Problem with ATF fluid W124 260E

[DREAMER NO2]

Back in 2014 i purchased a bottle of ATF for my auto box on W124 260E . Auto box type 722.3 722.4 722.5
The parts guy at the dealers sold me a bottle of ATF 134 .
I told a forum member on the forum in the USA . He said at the time it was the wrong type .
I did a check over the phone with the dealers and i was again told the same ATF 134 was the right oil . So any thoughts on this would be helpfull .

How do you mean ATF 134?
Is that Fuchs 4134? If so it's fine.

Lostkiwi thats just whats on the Mercedes lable on the bottle ATF 134 It is genuine Mercedes ATF fluid but i dont know if its suitable for the 722.3 auto box.

MB 236.14 so should be fine

 

[DREAMER NO2]

Yes that is the same as i have .. Where will i find information to say 236.14 is the right fluid ..I will look in my hand book for information . And if you are right then i did the right thing when i used it to top up in 2014.

 

[LostKiwi]

722.3/4/5 are pretty tolerant of ATF. Even base Dexron II is fine.

It should be in your handbook. I've used 236.14 in my 129 722.3 with no issues.

LostKiwi looked in the hand book and aldo in service book and would you believe it no mention of ATF specs it justsaid purchase recomended ATF fluid from Mercedes Benz . I will check it out further on the number you provided me with - 236.14 .Thank you LK .

Scroll down to 722.3 etc
236.1,7,9,10.
It doesn't say 236.14 but as I said they really aren't fussy.

LK still takes a bit of working out with the search boxes . I will need to look at it again to understand it better .And even now i dont see any information to say -- ATF 134 is good to go thank you

This is what I use in my 722.6 ATF4134 Merc 236.14 Fluid. (ATF134) And as stated above is "backwardly compatible".
This is actually used as a Factory-Fill.

Rhodie Bill So what auto box do you have in your car ? You see i have 722.4 09 and i still think its not right for my auto box

 

[DREAMER NO2]

I have done a lot of checking on ATF fluid for this auto box 722.4 and come up with so many conflicting answers .Some say use this others -that . And the one bit of information i found was that the M/B automatic fluid number ATF134 is for 722.6 and 722.9 type boxes . And that Dextron 111 is to aggresive for use in the 722.4 auto boxes . And to use the older type Dextron 11D if you can find it , this was original fill from new back in 1985.
As you say the 722.6 uses the same ATF 134 and if its backward capatable will that mean its ok like- 722.6 722.5 to 722.4 ?.

Now i have made up my mind to do a auto box service ,rather than topping up with unknown fluid, of one type or another . Gasket, and filter, along with sump crush washer .Just waiting for a listing number on Ebay to purchase these parts from Mercedes of Newcastle .Gasket is a special order part .

As for the ATF fluid i have gone for Castrol Transmax Dex ll D ATF . I use Castrol Magnatec 10w40 in the engine so i will stick with them. And you all made my mind up for me to change the ATF fluid so i use just one oil, then i dont have to mix it . I will be doing a normal engine oil and filter change as soon as the oil comes from Eurocarparts . Good deal at £18 .90 for 4 L. I have another tin in the garage to make up the quantity ..

a w124 could have a 4 or the optional 5 speed box. Out of interest did they 5 speed use the same fluid?

going back to the old world, although not a great idea, these fluids aren't that different
ATF, Dextron 2 and Dextron 3 are all auto box fluids so the ideas on lubrication, anti cavitation, wet clutch / bands etc is somewhere close. What's mildly different is friction levels and viscosity so it might not change as nicely and could wear a bit more.... if your life depends on it and you have to do 1000 miles no one would care

And that Dextron 111 is to aggresive for use in the 722.4 auto boxes . And to use the older type Dextron 11D if you can find it , this was original fill from new back in 1985.
As you say the 722.6 uses the same ATF 134 and if its backward capatable will that mean its ok like- 722.6 722.5 to 722.4 ?.

My 4 speed GM box in an omega was supposed to use dextron 3, idiot dealer thought and only sold dextron 2 and the same stupidity in the workshop .... had to do a special order to get the 3 in for me

this https://en.wikipedia.org/wiki/DEXRON says dextron 3H is backward compatible with all earlier versions and is designed to last longer and have less agro with TC clutch judder

Wish we had info like this for the Merc fluids and what their boxes really need

Botus i was reading a section from a latge gearbox service garage . They said if it is possible to find Dex ll to use it and went on to say that Dex lll was to agressive for the 722.4 auto box and that Dex ll was original oil that was used at fill up, back in the 80s
