Well I couldnt bring the car into the dealership until the afternoon so maybe that is the reason they suggested to leave it one day. Besides changing the filter and the add new oil (~9.5 quarts) I see that they should also install new overflow pipe and replace pan bolts.

If your car is fitted with the new pan & spill tube it is not necessary to do that again. I would not disturb everything again if it has a new filter either - the filter will be fine. Just get the fluid out of the transmission pan & TC & get a nice new charge into it & be done with it.

The revised pan & spill tube:

If this is a side topic , let me know... last week I was under the car and noticed some tranny fluid not really dripping but just lines like their was a very small leak... Took it in under warranty ... OH that is normal ... WTF ??? They called it sweating ?? Any of you ever see or hear of this ? Reading your stories I wonder if all dealers are just Crooks ..

Talked with a former owner... at 60,000 mi they had to do a seal (small O ring) on their leaking transmission ... $1500...

Glyn,

I just checked last year's repair order for my wife's 2005 W211 E3504MATIC. I also had only 5 quarts of fluid at the 39,000 mile fluid replacement. Do you know what model trans (5 speed) is in this vehicle and if it has the same requirements you have been discussing?

Thanks.

Hi,
Just got my car back today and can confirm that per the receipt they used 10 qts per the re-work. They did not charge me more. I am glad after the useful information from this forum my dealership was very cooperative and did the job. Thank you all!

SS ~ The 722.6 5 speed transmission fitted to the W211 has no TC drain. If fluid was good you can get away with half change or do a 14 quart flush. You have Wiki access. I have posted the flush procedures under 203 & 209 sections.

Even in a 722.6 I like a full change but it does not work it's fluid as hard as the 722.9 does & is a less fussy transmission.

Hi haptel44,

Good to hear that. Lucky you. At least, your dealer had guts to admit their mistake and redid it right.

Unlike the "stealer" I went to, they just tried to cover-up with a load of crap.

Quick question guys.... Is there a time limit for tranny flush or just mileage limit of 39K. My car is almost 4 years old and at 33K miles. Should I wait till 39K?

I think the time trigger is 10 years in ROW. I would wait

Playstrings my car had the leak too and i took it to one dealership and they said that the car was just sweating and I'm WTF i never heard of that but then i took it to a different one and they said that had to change the seal on something i can't remember now cause i don't have the invoice with me, but tomorrow im bringing my car to get a transmission oil change and I have printed all the papers possible that I would need to explain to the service advisor cause they keep telling me that they dont drain the torque converter and transmission service is $475+tax. Glyn M Ruck thanks for all the info and now let's see how it goes with this dealership!

Last I checked, sweat comes from glands to lower body temperature. Not from gaps in a seal that is used to PREVENT leaks.

Sorry I missed this thread before. I can't get over how many of you are having such issues with the dealers doing the 7G service properly. I just checked, and the WIS document posted in my service thread, is STILL the current WIS document. I have an active WIS.net account. I don't have access to Startek, for the "current bulletins" and such. But, I do have an acquaintance that does, and there are no current bulletins stating to NOT change the fluid in the torque converter. So the dealers that are stating us such are lying. As you can see by the WIS document, draining the converter was added in April of 08. So, the dealers have had more than enough time to read the updated WIS documents. They are REQUIRED by MB to perform ALL repairs and services to the letter of the WIS documents. All MB techs have access the WIS. I think we need to have people filing formal complaints to MBUSA when the dealers are not following WIS procedures. The 7G is too damn expensive to repair for incompetence like this.

OK, rant off

As an aside , those servicing their own 5 speed ATM's will find that they will drain an extra 1.5 litres of fluid if they leave the system draining overnight or for an extended period.

I drained a total of 5.75 litres over an 19 hour period which was 76% of the total fluid ( 7.5 litres)in the system.

So if you are not doing a flush an extra 20% if drained overnight, is worthwhile.

This is BS. On separate post I was inquiring about need for 40K transmission service on a lease car soon to be turned in. As an auto enthusiast and engineer I wanted to do the right thing although I think this service and brake fluid change every 24k is overkill aimed at extracting $$ out of customer wallets. This apparent confusion over 'correct' service reinforces my feeling that this service is lightly regarded by MB dealers. I personally think the 'half-+++ed' service (partial drain)described is pointless with potential to create more problems than help. I don't think it should be our job to monitor service practices and become involved in a war of service bulletins in the hope that maybe our cars will be properly serviced at high cost.
Very dissapointed in MB approach. JMHO

MBUSA & many dealers are clueless.

I have provided the global WIS document on servicing the 7 speed. Your dealers just lie to people.

Fortunately there are some that do the job correctly.
Well, I'm still overseeing service to the C300 (purchase mid summer '08), even though it's more my ex's than ever after recent, amicable split.

She dropped if off for the 7 spd oil change. I emphasized that the TC must be drained. I called SM (who used to be a tech there) at dealer. He looked at the same two wis documents I got here from Glyn. He said they rotated the engine and looked for the drain screw after removing the rubber case plug .... no drain screw was seen.

He said it's not that unusual for a 722.9 not to have a TC drain plug screw. He even interpreted the general wis document, line #6, column #3, to be conditional regarding the TC drain plug: "Vehicles with drain screw on TC, except on trans # 722.93" implying that some vehicles don't have the drain screw on the TC, according to SM.

He also noted that some tech's don't want to do it, as it's impossible to prefill the TC in place, and you would be starting the trans with no oil in the TC. True?

He may have a point if the TC housings varied, with and w/o drain plugs.

This car is a 4Matic, fwiw. Glyn, are you sure enough about this for me to challenge the dealer to redo it while I observe; no drain I pay labor.

Kevin,

See my last post in this thread: https://mbworld.org/forums/c-class-w...fferences.html

I ran AkaSigFreaks VIN through CURRENT WIS and EPC net, and it lists a valid part number for drain plug and WIS documents say to drain the torque converter. It is my understanding from talking to the lead tech at my local dealership, that EPC should be dead accurate. It uses engine and transmission serial numbers when inputting a VIN. If there is a change mid cycle, the affected serial numbers are updated in the database.

If you would like me to run your VIN through EPC and WIS as well, just PM me. Being yours is a 4 Matic, and you say it is a 722.93 (Eric's was a 722.999), there may be a difference.

Like I have said before, the drain plug in the torque converters are VERY easy to miss.

Thanks for the quick reply. The 722.93 was not our trans#, but was a model mentioned in the bigger pdf from Glyn.

Also, how do you put the new TC oil in?

And, was there a part# change in TC's around 2008?

Here is the WIS document on how to drain the converter - simple! Please note that when they talk about a drain on the 722.6 they are talking pre 1999 before it was removed.

All 722.9 transmissions fitted to W204 have a TC drain.

https://mbworld.org/forums/attachmen...-converter.pdf
When this link popped up a WIS proceedure to remove the TC drain plug, it showed a different bell housing, vs the other WIS trans drain proceedure link. Is this significant?

Just got off the phone with the local dealer parts guy. The techs have to get filters, gaskets, etc for the trans + TC oil change from the parts counter.

He looked up the part number for the torque converter (TC) for her 2008 C300 4MATIC. It's 001 990 11 17, and he said the pic showed a drain plug, and he thought the TC was for all W204's . He also said they have never sold a plug to the techs (reused old one?), and he thinks they always use about 5 Qts of oil.

That link goes to the VIN decoder. We are having link & pic problems on the forum. Bell housings change with engine application. Access is the same in all bell housings. Rubber plug.

All W204's TC have a drain. Only old S Class with 722.9 did not. If you want to reuse the plug you need to use a sealant on it. If you saw a new one you would understand. John can verify. He used a new one.

5 quarts is just a pan change. The TC itself hold 4 Quarts+.
