Here they are. Crispy.
Sheared aluminum bolts
Wrong trans filter
That filter part number looks like A2212770195. I cross-checked and seems to be for the “Mercedes 7G-Tronic” early non-MCT builds - “Mercedes E350, C300, SL500, ML350, S500, GL450, S550, C280, GLK350, S430 & more”.
Is said shop that did the original trans service in northern NJ? I was planning to go there for the trans service early next year, but I'm second guessing.
I wonder what my 2010 non MCT discs look like. First season of track only under the belt and it "seemed" fine but I did peak at 115°C the one hot day. Hopefully the Weistec pan will reduce those temps and I plan to dump the pan and refill every time I swap out the engine oil.

I’m sure you’re fine. This is many years of abuse (and a lot of heat in the early years). Probably 20k miles just on track. I’ll tell you this though - auxiliary trans cooler is my very next project and I’ll start on that as soon as I get the car back.

Honestly, the fluid change looks annoying and messy. Plus I'd like to relearn all adaptations and I don't have a scan tool that can do it.
About as messy as any other transmission service. Less so if you're careful and have the right tools.
Regarding a reset and manually setting your shift points, I have Xentry and am familiar/experienced with the process. Feel free to message me if interested.
Yeah bummer but I’m looking forward to moving past this with a better than new trans. They didn’t replace the wet clutch itself or any of the pistons - I thought this was a little odd considering that there was clearly heat damage as it was mentioned that the clutch packs were heat discolored. I wonder if I should ask them to replace everything before it’s buttoned back up? I might have time, but without more info I can’t really tell them what to do here. I told them I wanted it bulletproof, yet some things are considered ok and being left as-is. I wonder if this is the best course of action, I don’t want to do this again...
To my understanding, the sealed wet clutch unit isn't a weak point and I have been unable to locate any info out there on a rebuild kit or procedure. Curious to know what that shop's perspective is on it.

WTF?
I've been looking deeper into this and found some great info/resources on the 722.9 transmission.

-EPC, FCP and ECS list it as compatible with both the early 722.9 MCT cars (MY2009 E63, SL63) and the early 722.9 non-MCT W204 AMGs (MY2008-2009).
-The only constant the above cars share with regard to the transmission is a) the same shallower oil pan and b) use of red ATF 134.
-It is not listed as compatible with the later MCT-equipped W204s anywhere.
The most significant difference between the early-MCTs and later ones is the switch from red ATF 134 to blue ATF 134FE. None of the aforementioned filters are compatible with the blue fluid MCTs.
The ONLY filter anyone with a later MCT / MCT-equipped W204 C63 should consider is Part # 2222772000, replaced using the blue ATF 134FE and nothing else.
What a cluster...and a clear error made by the shop. Hope this helps.
That helps, interesting info thank you. Not sure what makes it incomparable with the blue, but it is, so that’s bad.
Anytime, happy to help.
Mercedes, as we all know, sometimes makes changes/updates to parts without any explanation provided.
Poking around Filtran's website and some release documents, the only real difference is that the newer filter has an additional layer (what they call V-Pore 97) that keeps air pockets from forming in the filter.
Best layman theory I have with the data available is that ATF 134FE is a lower viscosity lubricant and that using the older filter without this added layer introduced air pockets.
Could also explain why early MCT cars that came factory filled with the higher viscosity ATF 134 got away with using the older filter.
The wet clutch pack being a sealed unit, the implication is that the fluid that makes it a wet pack is sealed in with it.
The implication is that this fluid is another one of those "lifetime lubricants", which since the days of the BMW E36 automatic transmission lawsuit, we know that in corporate language lifetime= 100 k miles.
However for a track car, the ultra heavy service that the transmission is put through, then reduces the service life of the lifetime lubricant from 100k to .... maybe 60k.
Btw, drag racing and doing burnouts, donuts, drifting, can also accelerate the replacement interval of the clutch pack lubricant fluid.
Furthermore, a clutch pack is in the end a clutch.
Clutches are rated for an amount of torque. Once you mod the car and increase the torque output a lot, then the clutch starts to operate close to its torque holding limit. That must reduce its fluid replacement interval.
Now since the oil is sealed inside the pack, the only way to change the oil, is to change the pack.
Maybe this is why it's cheap, it's a consumable.
