I went to my local Fanfaro oil outlet to buy oil for my impending transfer case chain replacement.

They have two oils that have MB specifications but I want to know which one for my MY09 GL450.

ATF VI = MB 236.14
ATF III = MB 236.1 / 236.5

Which one is correct?

Thanks.

 

236.12

Fuchs Titan ATF 3353
Mercedes-Benz Genuine ATF MB 236.12

 

Thank you Sir.

I don't have ready access to those items here in Nigeria.

The plot thickens.

 

Redline D6 ATF meets 236.12

Both Shell and Mobil ATF 134 meets 236.14 and .12, someone please back us up if these are truly backwards compatible…

 

Maybe @E55Greasemonkey knows.

 

Thanks for all responses folks. It seems X164 is more common in the USA than Europe where Fanfaro is sold more.

 

This product cross references the Fusch Titan ATF 3353

TC uses the same red fluid from the transmission, which you may already know. I don't think it's super critical to have the exact spec fluid; the transfer case is nothing but a chain, spider gears, and large roller ball bearings inside and really no different than any other similar transfer case from Chrysler,Jeep, or GM for the last 20 years or so. Any red ATF will probably be just fine.

 

Thanks for your response. It actually makes sense. Like you said, just chain, gears, etc no clutch packs.

 

My TC is dual range with the centre dif lock. Does that still use the ATF you are discussing? I can’t find a reference to this spec TC in any of the oil spec sheets.

 

That’s where the 236.12 becomes important, or at least more important than the standard transfer case that has just bearings chain and gears.

fwiw I run D6 in mine.

 

236.12 for model 164 (yours)

Nothing specified for off road engineering package, which is what your two speed t/case with diff lock is part of.

 

I used Shell 134 atf in mine - same in my transmission. Bought from Amazon.

 

I think the rationale for it being the same fluid is in case the seal between the transmission and TC leaks, you want the same fluid in the TC as in the trans.

 

No.

236.15 is for the 7G-Tronic. Fuchs 7134.
236.12 is for the transfer case on 164 and 166. Fuchs 3353.

ML/GL/GLE/GLS have hang-on transfer cases and do not share fluid with the transmission. Sedan and GLC (I think also GLK) have shared lubricant transmission+transfer cases.

 

Ok so I`m a bit lost here, I have a 12 GL550, majority of online suppliers shows 3353 as the correct fluid but some shows its not compatible.
Which one should I use?
Any help would be appreciated.

 

Yes.

 

Just going to do an oil service on a freshly purchased GL500 with code 0430 "offroad package"

Table you provided is supercool - I'm just wondering what doeas the "*" sign means, and accidentally is just by the options I'm interested about - so the dual speed transfer case and rear axle with difflock.

Could you please provide any info as it seems that the explanation was there - it was just lost when you cropped the image

 

It only means that applies to the vehicles with the Enhanced Off-Road Package option.

Typical of MB, the option is listed even though the fluids are the same.
