Mercedes owned Chrysler for a while, so I believe during that time Chrysler vehicles used the NAG1 transmission.

Hi Gents
I realise this post is 3 years old but I have immensely enjoyed reading this. I hope you do not mind me resurrecting it?

I noticed a common opinion from some talented people stating that MB236.14 fluid is now the one to use in the 722.6.

Now my vehicle is an Austrian built Grand Cherokee. It has an OM642 Engine and a German made 722.6 Transmission (not a NAG1 made in Indiana). Jeep designated it the W5J400.

The service book and main dealer stress the correct fluid to use is ATF+4. I am really confused as to what was going on at Daimler Chrysler. Obviously someone up the 'food chain' of command deemed this fluid suitable for the 722.6. Oddly other Chrysler vehicles with the 722.6 were to use an MB236.12 spec fluid and not ATF+4.

Does anyone know why Mercedes, who were the parent company, allowed ATF+4 to be used in the 722.6. I presume there are many thousands of high mileage Jeeps running with ATF+4 without issue having had the original fluid changed out at service. This is assuming the 722.6 ones destined for Jeep production had Mercedes fluid as the factory fill and not ATF+4.

This would also suggest that ATF+4 is an approved fluid for the 722.6 as Daimler Chrysler at that time gave it their blessing.

I am not a chemical engineer so cant comment. But does anyone really know the real world difference between the various MB Spec fluids and ATF+4?

I would love to read some input on what I have written please. If I have made assumptions you deem incorrect please put me right. I am here to learn, not to be controversial or to cause upset.

Many, many thanks.
Nick.

Any ATF+4 will work well there.

MB 236.10 is the fluid for their 722.6 transmission, which is ATF+4. In fact, that same tranny is used in the Chrysler LX cars (which call for ATF+4).

I found out Mopar ATF+4 has similar viscosity indexes:

Type | Viscosity | @ 40C | @ 100C

Mopar ATF+4: 33.24 , 7.51

Shell SPIRAX S4 ATF 3403: 33.0 , 7.2 (MB 236.10 officially approved)

Drain and fill 722.6

Great info here. Thanks to all who contribute.
I recently purchased a W209 CLK500 with120,000 miles and no knowledge of it's maintenance history.
So I drained about 3 quarts of fluid from the transmission pan using the drain bolt. Added exactly the same amount back in if the shell 134 fluid.
I am now having some slippage at low torque then seems fine and a couple times under spirited driving it seemed to loose other gears.
Previous to the drain and fill I had zero problems.
Now, I was lazy and didn't drop the pan and replace the filter and gasket.
Not knowing the history of the fluid in the car, my plan is to now drop the pan, replace the gasket and filter and refill with shell 134.
Has anyone experienced this issue and if so how did you resolve it?
Thanks in advance
Thatch

At this point you have no idea how much fluid is in the trans.
GO buy a dip stick!

Slippage usually means low fluid especially since you had no problems betore. If you plan on keeping the car, do this properly once and for all. Drop the pan, replace the gasket the filter and the fluid properly and you're good to go. Otherwise, you risk damaging the transmission which will prove super expensive.

BTW I have been using the Shell 134 for about 50K now.
If you find after servicing the trans that it is good, I'll tell you about the 3-shift kits you need as well as the AMG Solenoids you need to wake that trans up!

Drain and fill 722.6

At risk of sounding like a complete idiot I'm posting this as a warning to others.
i also have a 2006 E500 with no oil filler tube. So I accidentally put transmission fluid in the oil tube in my clk500
Can't believe I did that as I have been working on Mercedes cars for many years but there it is.
I don't seem to have caused any damage but will be draining the oil and and filter obviously and refill. And performing the appropriate tranny service.
Just figured people might read this a be extra careful.

So all is well. Added the three quarts of ATF that I put in the oil and drained the oil.
then refilled the oil let it run for 20 minutes and drained that oil. Added fresh oil and filter. Runs like a scalded dog. I'll be doing the transmission pan and filter this weekend.
Thanks for the tips!

To clarify, I added back in the three quarts of transmission fluid in the correct tube and then drained the contaminated oil.
Hopefully I avoided catastrophe

What the Americans do with the transmission is their business - Benz does not have to carry the Warranty.

MBUSA are the idiots that said “filled for life” & it cost them. Stuttgart has never said this & ROW has always been on 60,000Km drain & filter. So don’t blame Benz engineers. They consider MBUSA to be a loose cannon.

Some companies are more reputable than others. All multipurpose ATF's are a compromise & do not meet any of the specs properly. Valvoline might consider that Chrysler is happy with their product. Benz is not. Valvoline do not say approved by Benz as it is not. Oil is not just oil. Today it is a design component of the vehicle. Same as a windscreen is no longer just a piece of glass. It is a stress component of the vehicle shell.

I have been in the oil industry for 39 years with the same company (see my profile). We do our research. I have worked with the MB approvals process on & off over that time & have been directly involved with ATF development to achieve Benz approval. I've been in & out of Benz test labs more often than you have had birthdays & Christmas.

I only give the best advice I possibly can on this forum to Benz owners. I do not just do what Benz says. I believe in the approvals program & have had plenty to do with it over many years.

You can do as you wish with your Benz transmission. Please don't give bad advice to others on this forum.
Glyn: I am a late comer here, interesting in your comments about the 236,10, and 14 ATF oil. My 2003 SLK320 has about 80K miles on it, and I am going to change the ATF now but have problem finding the OEM 236,10 oil. Most of the recommended suppliers have discontinued their products. You may ask why I did not change the oil sooner...Well, it is a sealed system with no dipstick, and MBUSA marketing suggested 100K or so miles. So you see, I am not tardy here, LOL.
I tried to look for MSDS sheet for the properties of 236.10 but could not find them, but I did find 236.14, and it was said to be a semi - synthetic oil, unlike the 236.10, I suppose. It appears to me that synthetic oil may have better viscosity control or lubrication than the non synthetic ones.. If I am going to use the approved 236.14 oil, there will be mixing of some kind, no matter what you do. Do you think that will not be a problem, even if the mixture can change the viscosity/lubrication property of the oil ? Also, as I try to look for the current ATF oils, I noted that almost all of them are full synthectic, like Valvoline Maxlife vs the Shell ATF-134 which is semi-synthetic. These two oils differ in viscoisty properties somewhat, and in flash point as well, but not that much from what I can see. Do you think that will cause any issue to the hardware/gears? The only thing that the MSDS did not say is the additives, which may be at play here, but almost all ATF producers will claim that their additives improves the stability of the oils...So what give? Trying to get OEM 236.10 oil for to prevent mixing problems or 236.14? or Maxlife because it does not matter anymore as the old ATF may have a lot of oxidation that its property has already out of specs that I am basically on my own...

I used maxlife and damn near destroyed my transmission. It's never been the same since. Never use any product is not approved by mb. Take my word for it, cheaper is NOT better.
