Tackling my first Service B and Transmission Service tomorrow...
The car is a 2009 C350 just under 60k miles. I bought it in November at 58,xxx miles. I have the following:
1. 9 qts Mobil 1 0W-40
2. Mercedes oil filter
3. New drain plug
4. New drain plug washers
5. ECS Tuning transmission service kit (comes with gasket, filter, oil, TC drain plug, etc)
6. Interior cabin filter/2 engine air filters
"Special" tools I have are:
1. Fluke 62 thermometer
2. 722.9 transmission fill adapter
The only thing I don't have that I would have liked to do is my windshield wipers, but that can come later.
In addition to the above, I plan to inspect:
1. Poly V Belt
2. Tires (rotate)
3. Suspension components
4. Driveshaft flex discs
5. Steering components
6. All fluid levels
Am I missing anything, or is there anything anyone wants to suggest before I tackle this? I did all my own maintenance (including valve adjustments) on my M3, and just did a transmission service on my wifes Charger (which has a Mercedes transmission) so I'm sure this won't be difficult, but I haven't done it before, so I don't know what to expect. I am using a lift, so that will make things 100 times easier I'm sure.
I will say the only thing I am doing that people don't recommend, is draining the oil the conventional way. This is purely related to my desire to save money this time around. In the future, I may buy a nice pump for the job, but right now I am doing it the old fashioned way. I am also using a small hand pump for pumping in the transmission fluid (one that screws directly onto the bottle, like a marine supply pump). Again, this is 100% due to lack of funds this time around. Nothing else

Actually, how are you going to do the electrical system check, including the individual battery cell status? While still under warranty, the dealer found a weak cell in my car's battery and replaced the battery before it became a "roadside" issue.
Per the above post, check out his list of all the steps as your guidance.

Ill have to get back to you on that one 
Thats a big help. Thanks. I think I got everything covered (all of the majorly important stuff anyway).
To anyone saying that I should have the dealership do it (not singling you out Sportstick (and I assume you were joking, but I know others feel that way) I choose to do all my own maintenance for three reasons:
1. I don't trust anyone: How many horror stories have you heard of dealerships and indy shops skipping essential steps, leaving things out, or flat out doing a job wrong? Assuming there was some type of gaurantee the job was done 100% correctly, paying the extra money for that piece of mind might be worth it. I just don't trust other people working on my car.
2. Why pay someone to do something I can do myself: I've probably downplayed my mechanical ability in my opening post. I feel 100% confident I can do almost everything (with the exception of a few inspections, which I honestly doubt are really done half the time at the dealership anyways) that a Service B and transmission service require, so why not do it myself and make sure it's done right? I'm OCD and know I will be meticulous with the job. Plus, it's my car, so if it's not done right, that only hurts me. A mechanic is in a rush to get the job done ASAP and is less likely to care if he misses something or doesn't do the job right (see number 1)
3. I'm frugal: ...but by no means am I cheap. Though I absolutely want to see the job done right and will pay extra for a peace of mind (see number 2), I like to save money where money can be saved (ie not buying a pump right away). This whole job is costing me roughly $400.00, and a good $100.00 of that is tools I can use next time around (Fluke and transmission fill adapter). So basically $300 for a full Service B and transmission service. What does a dealership charge? $1000.00+? And again, I know it's going to be done, and done correctly (see number 1)

I think the regular check up is 650+tax. I had to get a light wiring fixed and they flushed my brake fluid. I'm horrible with cars, so that is why I took it to them. Plus the fact that if something happens they will have to answer to it. At least in Canada they do their due diligence.

Make sure there is no lint left from rags around ATM .In fact I used a clean brush to clean pan.
Open up pan filter to view rubbish for interests sake.
Enjoy the experience.
I do have one concern..
..my transmission is the one with the angled front edge, and it had the white overflow tube. ECSTuning sent me a green overflow tube with my service kit. I'm not 100%, but after reading, the green overflow tube is for newer transmission pans (2011+)?? Either way, it was a good 1/4" shorter than the white one. My dumbass didn't think to reuse the white one (though I did keep it just in case) and I installed the green one. I wasn't too worried, but my concerns continued to grow beyond the point of no return (when I was filling up the pan with new fluid).
What are the concerns with this? Obviously the shorter height means more fluid drained out than what that particular pan and the white tube call for when I was draining the pan out before putting the plug back in. In order to try and compensate for this, I put the plug back in slightly earlier than I normally would have. When I pulled the adapter and the fluid started flowing, it was a very heavy steady gush of fluid which lasted for 5 or 6 seconds, then the flow was slightly tapering off, and was sort of swishing out if that makes sense. About 2 seconds after the steady flow ended and it started swishing out and tapering off I put the plug in. In other words, I didn't wait until it trickled out like you should, so there SHOULD be maybe 1/2 a liter more fluid than the green tube should allow for when it is properly adjusted.
I hope all that makes sense..I don't honestly see a difference of 1/2 liter more or less fluid than what is supposed to be in my transmission making a huge difference, but should I be concerned? I plan to do another transmission service in 20k miles, so would I be okay until then?
Any help is greatly appreciated. It will be a pain in the ***, cost me probably another $100.00 and **** me off, but if it's not a good idea to leave it how it is I will buy some more fluid and put the white tube back in and do it right.

Put the white tube back. Level is critical on these transmissions. You can always save & filter the fluid before putting it back in. I hope they did not send you 236.15 Blue fluid?
Your transmission runs 236.14 fluid.

Here is the kit I bought:
http://www.ecstuning.com/ES2696245/
Im assuming that fluid is 236.14 spec?
It's a little irritating that they even show a white overflow tube in the product picture. Oh well, back to the shop Tuesday. Better safe than sorry I guess.
Two questions:
Do you think I am okay reusing the sprag bolts? They are brand new, but have obviously been torqued down once already.
With the correct overflow tube installed, at what point do I put the drain plug back in? The instructions sort of leave room for interpretation. Do I want a slow trickle, occasional drops, etc?

Seems the fluid is correct although I hate to tell you that Febi Bilstein do not hold a Benz approval.

You cannot use the old aluminium pan bolts. They are use once stretch bolts.
Regarding level. As far as I'm concerned you put in enough fluid to achieve a clean running stream of fluid from the drain & plug it when it's slowed to the odd drop. John has more experience of physically doing the job than I do so listen to him.
The reason I used the green tube instead of putting the white tube back in is I figured the green one was just an updated version of that particular part. Auto manufacturers update parts, change procedures, and rewrite standards all the time so I didn't think too much of it. I knew there was a difference between the black and white tubes but never did read anything about the green tubes until the job was almost finished.
Oh well. live and learn I guess. its any easy fix. Shouldn't take more than 45 mins.

It's a good learning experience IMHO. Intuition was spot on.
This mans limitations are a lot less than they were. He is now experienced at servicing his MB. Unlike many.
Good luck to you |||||||||| what every your call sign is .You have had a go & won !!!!!
|||||||||| , what did the inside of your filter look like ?
Is there not a dip stick tube to double check level in the case of a seal leak etc.?

If you have to drop the ATM oil again I would change it to the MB approved oil for piece of mind. It will be in the best interests of your car in the long run.
In fact I would take the Febi oil back to where you bought it & get your money back. They sold you the incorrect oil & should be told. Here is their spiel :- "which is why we have created this Automatic Transmission Service Kit for the 722.9xx series gearbox. "
Sportstick, I now understand. Thanks.
