Mepeh,

The dealer fluid, stay away from it as it rated for 722.9 trannies and 722.6 owners complained of accelerated wear to failure in a year or two, so even if the stuff is a penny a quart, walk away...

I saw your post on benzworld, and I replied to it about the scan tools. I too am on the same fence, but I have not pulled the trigger to buy it. I would buy it from these guys, and one great member there made it work with no problems.

The seals, I have to find the link on my other computer. For the life of me I cannot remember. I know DACCO transmissions may have it and precision international will defiantly have them. Here is the DACCO one:

Let me check my other computer and Mercedes EPC, give me a day or two.

That's great help. Thanks
I just placed my order on obd club for a C3. It's confusing on their site how they call same models with different names. I would prefer to go through ebay in these cases, but the only guys selling there have max 5 feedbacks. And it's something you will definitely need support for. And Vivi replied to my emails pretty quick and advised which one exactly to get.

I'm afraid Carsoft will be more headache then the MB Star C3. I've heard of issues with C4 due to it's wireless connectivity. I have the wireless option on my BMW tools and it's much slower on wireless then cable.

Thanks for the links, will have to look into that and order.

I know the flex disk was recently replaced, will have to take a look at the bushings

Solenoid Covers. Are you talking about 459 and 459B in this diagram ?

Received the first packages today.
Placed the order yesterday

I think this is the best part of the hobby. Buying parts and seeing them on the porch delivered. Buying wheels must be a pleasure for everyone here.
The second best part is selling your old parts and getting more then you paid for the new replacements.

Have to mention 3 of the 20 bottles got damaged and leaked fluid in the box.
In no way i want to make bad advertising to the company. They have been great all the time. Never missed a package. Always receive the next day.
Will see how CS will handle the issue

Martin, what does MB have available for the 722.6 transmission if it is not the 134 fluid they currently sell for the 722.9?

Conductor Plate. 1402701161
Incorporates the Plunger, the circuit board to the actuators, the speed sensor and the connector that you see leaking on the outside through the infamous seals

MB does not sell the old 236.10 fluid....(001-989-23-03-10)
ONLY 722.9 fluid 236.14 --> 001-989-68-03-13
They STATE its backward compatible, but the fluid properties are different. The 236.10 is a variant of Dex III that is more compatible with the electronic components inside. 236.14 is much further away from Dex III.

My recommendation -- do not use it.

Go with the OP's choice of Titan 134, or Shell 134 found at Ryder Fleet Products . com
They have it listed as Penzoil, but its Shell and its perfect for 722.6's....12qt's for $70. Win win.

Changed the CLK320's at 103k, original fluid in it, no issues shifts great going on 10k miles now.

Others say Walley world Maxlife Dex III is fine and no issues, but no information from anybody going over 100k with it, so not worth the risk to save $30 per change. Intervals every 60k should be fine.

Yes those 459 & 459b are the covers, see if they are maybe on your solenoids already in the trans, I don't see them with the new part, they used to include them with it.

Glad to find that out about the fluid in regards to the 722.6.

Thanks Gilly. The only place that sells the magnet online wants 11$ for shipping. I guess i'll just stop by the dealer and buy it

Regarding Penzoil/Shell Oils, please someone post a link where i could get it
Ryder doesn't sell it anymore, and the link everyone posts to the Shell oil, well that requires a customer code now that is probably provided to wholesalers only.
I'm still waiting for them to get back to me with instructions on how to obtain it

Wolfs Head transmission fluid

Anyone ever try this stuff?

Just because it states it is 236.10, it does not mean it is APPROVED by MB for 236.10 standards. There are plenty of high quality fluids out there that are MB approved. The use of anything else would either be worse, or at the very best, have a negligible difference that will more than likely go unnoticed.
Some say its marketing so it forces you to purchase the product from companies who are financially affiliated to MB, but at the end of the day, its up the user if they want to save a few bucks on a multi-thousand dollar transmission.

When it comes to regular oil, i can play around and try different brands.
When it comes to Mercedes Transmission Fluid, Mercedes SLS Fluid, i'll go with what was tested and recommended mostly on the forums.

Mercedes Label, Fuchs or if you are on a really tight budget, get the Shell (if you can find a retailer). Too bad there's no Mobil Fluids for transmission, i would definitely trust that brand
