At very least, be sure that you have paperwork with the compaint specifics from the dealer. Take it in two or three times under warranty, it should give you what you need to show that the problem existed under warranty. Documents, documents, documents.

That's pretty much why I took it in today. I don't expect they will be able to experience the problem; the car needs to be fully warm and even then it's a bit intermittent. Maybe SDS will show something awry - assuming they look at adaptation numbers and don't just look for error codes.

Problem with the shotgun approach is they charge a ~$100 diagnostic fee if they don't find a problem covered by Starmark.

Reading old posts, seems there's a good chance it's just a little low on fluid. I'm hoping they check that - I don't have the dipstick tool. Nothing on the garage floor, but I haven't been under the car either. Trans has never been serviced; dealer says MBUSA never issued updated maintenance schedule and refuses to perform routine servicing on it. Seems to agree with what I've read in the archives; many countries changed to require servicing at ~40K miles, but not USA.

Not correct; MBDOC has posted the docs previously. IIRC W210's wern't on the list as they were out of production when the doc was issued.

just to add my little bit of useless knowledge - but I find these cars need a GOOD battery, or else funky electrical issues occur - and these transmission are computerized electrical gizmos.
I had trans issues on my 2002 C-class, and it was due to a five year old battery that wasn't used often.

I'm searching old posts but not finding that. See this thread in which Mr. ILUVLMILS states that a single transmission service was added to the 2006MY cars at 39K miles, but does not appear on the service sheet for earlier model year cars. See post #5: http://www.peachparts.com/shopforum/tech-help/127872-transmission-service-larry-others-post924260.html

There is also Gilly's infamous "we didn't say who's life" document, see post #8 here: http://www.peachparts.com/shopforum/tech-help/102541-1999-s500-722-6-automatic-transmission-filled-life-post702285.html#post702285 But again, no general service interval is set for the 722.6.

Can anyone find anything different?

BTW, the car has a 1 year old battery, so funky electrical problems it isn't.

See #41 & 45. Transmission Failure 99 e300TD

I might have the doc saved at home. As I recall it did not inlcude W210's specifically as they were not in production at the time.

OK, that's it then. Looks like the omission of the 210 chassis was a typo, nothing more. It's interesting to note the main focus of the SI seems to be preserving shift quality, not transmission life. Thanks for pointing this out.

So, how annoyed do service advisors get when you point stuff like this out to them?

In hindsight, rather than a typo, I suspect it had to do with the fact that at the time the doc was written the W210 had ceased production and had already been replaced by the W211.
