Took my '06 E3504matic into dealership for 39k service on transmission and 4matic. They flushed the transimission fluid and didn't change the filter. Is this consistant with the factory requirements?

Transmission flush? My professional opinion is, do not do it. In my opinion there is trash in the filter and in the bottom of the pan, if you flush you disturbe all those metal fragments and push them all over the inside of your transmission, I think it is a big gimmick it,s fast and it earns them money and leaves your transmission questionable with metal fragments in places you don't want in O RINGS, SEALS, CLUTCHES. BEARINGS. come on if your transmission is due a service drop the pan, change the filter. drain the torque converter, and adjust as needed,and add new fluid, thats what is called for.stay away from flushing anything, not good. and if your transmission is acting up get it checked out by reputable qualified mechanic..

Are you telling me that a Mercedes-Benz dealership would perform an unauthorized service procedure on my in warranty Mercedes-Benz?

an 06? shouldn't that be under factory warranty?

The flush is done on the newer cars without torque converter drain plugs. Otherwise you're only exchanging about 1/2 of the trans fliud during service.

I guess I want to make sure that it is an authorized procedure because the maintenance book says to change the filter. I'm ok with it if it is sanctioned by Mercedes.

Most dealers do flushes now-adays, and call the old method "outdated". I chose to do my truck myself so I could change the filter. Having said that, I had a shop flush the system in my wife's car, but I asked them to also drop the pan and change the filter, so its obviously possible to do that way as well.

Yeah, that's why you drop the pan and change the filter, too. The dealers ONLY do a flush, and leave the dirty filter in. I've never understood that, that's why I don't get it done there even if they're running the $129 "Special" for it. I service my "filled for life" 722.6 every 15k or 20k, but I also have the filter changed, I don't just do the flush only.

Also, when you get a new car, it's a really good idea to put in one or two pan magnets to accumulate all the crap and metal shavings. I don't believe MB's come with them from the factory. Once you get some mileage on the car (10k or so) it's worn-in to where the metal shavings aren't such a problem, but when you first get it the motor and tranny both will produce a lot of shavings and the magnet helps.

You should have the filter changed as well!!

MB has changed their position 3 times on their "sealed" transmissions & for 2009 suggest trans fulid/filter changes EVERY 40K miles!

IF you want to keep that car, HAVE the trans serviced at least that often!

Thats just my professional opinion of 36 years , I have seen them flushed today and back a week later with shifting problems, so how do you argue that. Not just one car but many cars? so there must be a problem with doing that. that is like draining fluid out of a dip stick tube I can do it and have done it many times for transmissions and engines saves a little time makes it easier and cleaner but does it do the same thing it removes most of the fluid if I was pulling a tranmission for overhaul I could do it before pulling it. my whole point is serviceing a transmission is pulling the pan and examining the metal particles and fragments and changing the filter.we can argue this all day,its just and opinion, like doing a brake job on one wheel I can do it but does that make it right, No it sure doesn't.

So the 9/05 document changing trans service on 722.6 & 9's to ONCE at 39K miles has recently been revised to service EVERY 39K miles?

Can your post that document? There are SO many unbelievers and even dealers who refute it requires service.

Hey if you want more confusion my dealer wants to do it every 52K miles.

more confusion. as an indy, i've tried REALLY hard to stress every 60k, fluid and filter. seen a few transmissions survive doing that while seeing others follow the EARLY mb lifetime schedule. i am encouraged that mb now thinks otherwise. and so it goes, chuck.

Yes, in the plants like the Chrysler Kokomo transmission plant or the Ypsilanti GM Hydra-Matic plant, those are called " Van Wert donuts" in honor of the Oilite Company's powdered metal plant that made millions of round magnets, even made some in odd sizes for tractors.

I conducted a mgt tng program there in 1982. Great people. They were in the middle of Ohio, "half way between Venedocia and Ottoville, ya can't miss the blinking light!"

The only manufacturing plant I know of that offered employees a 10 x 10 plot for a garden on the front of the company property!

But all those traditions are gone,
unless the PRC's Ministry of Labor offers that deal to the employees of Sintered Metal Factory # 5 in Bongyang or some other place

You realize of course I'm not the one who defined what was done. The Mercedes dealer did. What I am trying to find out is, is the Mercedes dealer following Mercedes recommended maintenance practices. It seems to me that they are obligated to in order to keep the car under warranty. I would really like to hear from a tech who currently works at a dealership to understand this.
