There is no special tool that was indicated on the MB repairing booklet. Before drilled the hole I tried to make some different tools, all failed. Dilling a hole is the simplest method.

I bought a small torque wrench for this work. That's my 2nd torque wrench.

1st trans oil change was 10,773KM on 15 Aug 2018, but 4 years of oil age coz car is 2014 model.
Damn, gearbox suddenly became much more responsive. I kid you not.

However, the 1st oil change I did not get to remove the oil in the torque converter due to start-stop trans oil pump blocking the drain hole.
This 14th Aug 2020 is the 2 years and estimated maximum 23,500KM. So 13,000KM ish I get for 2 years oil life.
Today 30th May 2020 mileage is at 22,150 KM.
To reach the drain screw of TC, you have to disconnect the auxiliary ATF pump. Here is the documents of the entire process pulled from MB WIS. https://en.leighsr.com/mb-7g-atf-change-w212

Since we are talking about Transmissions services...
I noticed on the FCP Euro site that the filter for 2011 and prior is different - (A 2 stage filter vs after was a 4 stage? But you need the deeper transmission pan (Also included in their kit)
Does anyone have any insight in to doing this upgrade? I feel like this upgraded filter is if coolant gets in to the trans fluid? I thnk also you gain about another quart of fluid.
Is this like slipping on a extra condom for protect?
(I have no affiliation with FCP Euro and did not want to link it - dont want to get in trouble)
Thanks in advance.

I personally don't recommend this upgrade. Because we do not have the ability to test the pressure, capacity, and flux that is good or not good for the condition of running transmission. So I would rather respect the original design.

There is only the Oil Guide Pipe part number (A221 270 76 04) on the EPC. The O-ring was attached to the oil guide pipe. Not a separate part. I can't find the part number.

Part numbers for the o-rings is 0199975845 and you need 2 of them. FCP Euro has them.

I just double-checked the FCP website and EPC part number. 0199975845 is Transmission Oil Cooler Hose O-ring, not Auxiliary Pump Guide Pipe O-ring. See attached screenshots. If you ensure that's samething, that would be great.

You are correct I'm sure. I wonder if perhaps they both use the same o-rings?? Hard to know if there's no listing.

Newbie question: it seems a lot of fluid drains when the plug is removed from the pan, but at the end the goal is to fill only to the top of the overflow plug. Is this because the engine is running during the fill measurement step?

It is different. The aux trans oil pump's pipe/tube seal is below. I took the photo today from my E400.



Lucky my torque converter oil drain plug is not like Bro 39039, mine at the center of the service opening

Manufacturer knows thru trial/experience that when the fluid is at the specified temperature and the oil level is at the top of the plastic plug, and engine is running in neutral, that is the correct level for the ATF. If you had a dipstick, and it was marked full on the stick under the same conditions, the fill level would be exactly the same, and you could use a dipstick to check your trans fluid level. But people don't check their transmission with a dip stick only when the temp is at that precise temperature and they have no easy way to tell what the trans fluid temp is when they are checking.This is the Germans being precise, something they do very well.

I just know if the 722.9 has replaced the trans oil cooler, that'd be different from correcting the oil level without a trans oil cooler. Bring the oil temp to 90C/194F to let the thermostat opens and then cool down to 45C/113F to correct the oil level.
Hi. Could you pull out the ATF changing guide from WIS of MB vin WDDHF9AB8BA472746?
many thanks

Am I understanding it correctly? Based on the video after emptying torque converter and atf pan it requires to pump initially 9 liters of ATF before turning the vehicle on to gain up to certain temperature.

Take a note.
To read trans oil temp, a regular OBD2 can not read that temp data. I have Torque Apps with OBDLink LX.
But my icarsoft MB V2.0 can read the trans temp data.

If one get it wrong and in fact trans oil temp has hit more than 65C and then you start topping up, you may end up short filling by 0.5 liter. That is the experimental value I measured last trans oil change.
How accurate an infra red thermo gun shooting oil pan metal ? I don't know because refraction value error of infra red based thermo gun and time for the metal oil pan to equal trans oil temp, I can,t say.

He initially recommends pumping 10 L fluid. Overfill it and let the extra fluid come out.

I've been looking for that answer for quite a while now and I got in touch with the thread owner on YouTube. Thanks to all for the great information.

I've been searching for an answer to that same question. I have seen that video the thread owner posted a few times now.

Here's my process question:
1. So I drain the pan, clean it, put it back up with new parts.
2. Then I drain the torque converter, close it up.
3. And then I pump the ~9 liters of ATF
4. Start the car and let it reach 45C temp and let the excess fluid out.

Is that how it is supposed to be done, right?

They don't have to be done separately, right? The pan and torque converter can be drained altogether and refill at once?
Actually I drain the TC first, also was list on the WIS.
I upload all of documents of ATF change were pulled from MB WIS on my webpage https://www.leighsr.com/atf-change-7229
You might see the sequence is on the link above.

Ahh, I see. TC first and then the Pan. Got it.
Yes, I have that link bookmarked, just hadn't had the chance to read through all of it yet. I'm going to bleed the brake fluid first and then focus on the ATF change.

Another question, the pump I saw you use is from Home Depot, what was the size of the tube that you connected to the pump and the filler adapter? Also, I don't have the XENTRY tool, it's quite expensive, what's the other method to check the ATF temperature? I take it that the temp gun isn't as accurate.
