Automatic Transmission Fluid

[lawser]

Ok i've posted this elsewhere with no success perhaps the good folk on here can help ?

Can anyone tell me if there is a difference between using Comma AQM ( Dexron11 ) transmission fluid and Dexron ATF in an automatic gearbox ?

Make absolutely certain that the box needs Dexron.

The Citroen 4HP20 uses ONLY Esso LT transmission fluid and anything else will ruin it.

Not too sure about the other autoboxes.

Well now i'm confused as the manual states that i need Total ATX fluid, how do you compare all the different types of Tansmission fluids ? <_<

This may only add to your confusion, but a good read all the same...

To confuse you even more, my Saxo manual says Dexron type ATF

[myglaren]

It certainly is a confusing issue. I put in the proviso for the 4HP20 box as anything other than Esso LT is lethal to it.

 

As with the manual boxes, which should only have Total BV 75/80w in them, anything else will kill the cones.

ok so how do i tell if my gearbox is knackered or if it's something repairable ?

It is pretty much all repairable, just the cost can be a problem.

 

If it is lurching when changing or locking into certain gears then you have a big problem.

 

Some faults can be remedied with a diagnostic computer (Lexia)

 

Have a read through this thread for an insight into rebuilding a 4HP20.

 

Brief Encounter II (anything but brief)

The 4HP20 transmission is made by ZF in Germany.

I have noticed that many people are confusing and wondering what fluid to use for those transmissions.

Many manufactures uses transmissions from ZF. All of those manufactures are only recommending "their fluid" as the only ones suitable for those transmissions.

If in doubt, then it is always safest to check what the manufacturer tells is okay for their own production. This you can do by visiting their homepage www.zf.com

Then look up "Manual  transmissions, double-clutch transmissionsand automatic transmissions for cars" > and click on the TE-ML 11 link.

Now look up the transmission you desire to find what fluids the manufacture recommends for it.

In this case we are looking at the 4HP20:

It needs fluid categorized as Lubricant class 11B:

Here is list of manufactures and undertype of fluid they provide in their product line, and ZF recommends for this type of transmission:

 

AMALIE PETROQUIMICA, MADRID/ES  -  ATF DEXTRON III

 

ARAL AG, BOCHUM/DE  -  ARAL GETRIEBEÖL ATF LD

 

BP PLC., LONDON/GB  -  BP AUTRAN LTF

 

CASTROL LTD, LONDON/GB  -  CASTROL TRANSMAX Z

 

DEUTSCHE PENTOSIN WERKE GMBH, WEDEL/DE  -  PENTOSIN ATF 1

 

ENI S.P.A., ROME/IT  -  AGIP DEXRON III

 

EXXONMOBIL CORPORATION, FAIRFAX, VA/US  -  MOBIL ATF D 21065

 

EXXONMOBIL CORPORATION, FAIRFAX, VA/US  -  MOBIL ATF LT 71141

 

KUWAIT PETROLEUM INTERNATIONAL LUBRICANT, ANTWERP/NL  -  Q8 AUTO 15

 

TOTAL LUBRIFIANTS S.A., NANTERRE/FR  -  TOTAL FLUIDE AT 42

 

YACCO SAS, ST PIERRE LES ELBEUF/FR  -  ATF III

 

ZF FRIEDRICHSHAFEN AG, FRIEDRICHSHAFEN/DE  -  ZF LIFEGUARDFLUID 5

 

...Of course there is in some cases that those fluid manufactures are now selling the same product under different undertype name. But usually it is easy to get this type of information from the local distributor or simply look it up, using the Internet.
