The book says the transmission and 4 matic need to be serviced at 39k. Dealer says wait until 52k. What should I do?

lkchris

Do it at 39K as Mercedes specifies.

TMAllison

Service Information S100.20-P-0022A dated 18.2.05 says service at 39k miles "one time only" for trans. Applies to both 722.6 & .9 trans.

I just did my 07 E350 at 39K, the dealer insisted that it was unneccessary as the transmission is sealed for life. Yeah sure!
Paid about $300 for it at the dealer.
I have the extended warranty and didn't want any problems down the road with the dealer saying I didn't comply with the service requirements.

Taking it in Monday

that's interesting because on my 500 the only thing at 39K is the SBC brake flush on the C service ( I think it was C) no tranny flush as I recall only brake flush 150 bucks +/-

the trans.And the service required at 39K is a TSB directed to dealers to satisfy demands from owners about poor shift quality on the 722.6.
Your dealer needs to read his TSB's.Or find a different dealer,or Diy drain and fill.MB spec fluid only,autohausaz.com Has the filter and fluid and I have the dipstick and magnet.

starcarnut

Sorry, I'm a little confused. Are you saying not to do the flush at 39k or do it because of the TSB?

007_e350

I didn't know the trans service was recommended at 39k .. I'm at 46k, would want to get it done but I dont trust the dealer (MB of Westmont) .. He screws up anything he works on ... Do we know what exactly will be procedure is for this service (I cant think of anything but flushing ..

thanks

I'm at 45k, just got the car and don't want to miss something I should do but neither do I want to do unnecessary work. Was thinking about trying this myself, prefer to do as much of my own work as I can.

TMAllison

Is almost impossible for some of you with newer 722.9's to DIY.

There is no fill tube; requires a pump to refill the trans through the "drain" plug on the pan.

starcarnut

Can't do it thru the dipstick tube? Is the 722.9 the 7-speed in 06 and up?

steveberde

My error on this - after checking the owners manual it's very clear that at 39K a transmission change of oil and on the 4matic a transfer case service is required - very interesting - I had mine in for the 39K just a month ago and all they did in addition to the oil service was the SBC brake service flush -

Hmmm - I'll contact them Monday and find out more about this -

Ok let's get our facts straight here. I am looking at my 2006 E-Class maintenance book right now. On page 50 it says at 39k 3 years perform the following services. 11 with note 1,12,13,20 with note 7. Note 1- not mileage dependent only time interval applies. Note 7 - not time dependent only mileage interval applies.
US Service 20 once at 39,000 miles:
Underside of vehicle
Automatic transmission - oil and filter change.
Transfer case - oil change (4MATIC only)

So in my opinion it is more than a TSB driven activity. The question that remains is exactly what is required to remain in compliance with the warranty.
I don't want to pay for a flush if that's not required which is what I'm sure they are going to do. I'm sure that I can drop the transmission pan and replace the filter if that is all that is required. What about the torque converter fluid? What is the service for the transfer case oil change. Is that a flush or an easy DIY?

konigstiger

MB required ATF and transfer case change @ 39000.

Here is your vehicle’s MBUSA maintenance sheet for warranty compliance: 05-08 maintenance

Thanks Konigstiger

Had the service done by the dealership. They flushed the transmission and didn't replace the filter. Does this meet the factory service requirement?

konigstiger

Absolutely not, service sheet requires transmission fluid & filter change.

I almost forgot to do this for my C. It seems quick though to change it at 39K. At least, I won't forget for my new E when I reached that milage.

MBNUT1

So now what do I do? I did bring this issue up when I filled out the survey. I requested that they show me that this was per Mercedes procedures and so far have gotten the run around. How do I contact Mercedes? My thinking at this point is to go in and demand that they provide documentation that this is per Mercedes procedure or they do it by the book free of charge or get Mercedes involved.

konigstiger

Request to speak with the service manager of the dealership if this fails to resolve the matter contact MBUSA CAC (customer assistance center) 800-367-6372.

MBNUT1

The service manager is the one giving me the double talk. What documentation should show that this is a factory autorized procedure?

gnma

See post #15.

I can't imagine they'd change tranny fluid and not the filter - maybe they were out of them and didn't want to wait to get one in - it's just a drop the pan and change it process - 7 qts of tranny fluid I believe it was - plus like a qt for the transfer case on the 4matic - 300 bucks for all - It might be my imagination but it does seem to shift smoother though it always was pretty smooth - now it's totally seamless -

Got a question about the new valve body. Took the car in for service and mentioned that my tranny was a little abrupt in the upshift and after checking it over, the dealer changed it out. It still seems to be abrupt though not as bad. It's only been a couple of days, will the software adapt after a while to give better shifts or is this as good as it gets?
