Will do it anyhow. One of my friends has a 2002 E320 and she just did her tranny (first time) at 100k and her tranny has never given her problems so maybe it isn't so bad?
I would just rather be pro-active and service it before the 100k. I would hate to see what they would have found in my fluid. I wonder what the recommendation is for the 2007 E class? Musikmann did they say at 90k miles a full flush is recommended?
Hello again Debbi,
One of the dealers I talked to recommends it at 100,000 and only earlier if they have it open for some other reason anyway; then they change the filter, and I presume just replace the amount of fluid that is lost. The other, and the one who just did my service, recommends it "somewhere" between 50 and 75,000. Blackstone's advice is to do it at 34,000. M-B told me never
in that email that I used to start this thread.
In my opinion, you are set for another 30,000 miles, just like the guy at Blackstone told me. I have about 60,000 now so that's where the 90,000 figure came from (30 + 60). I'm sorry if that was confusing, and I was not prefectly clear during that interchage with Jayhawk.
As far as your friend, she might have been lucky. But, if that was the 1st time she probably should have had it analyzed.
I think now, at least on the gas burning cars, M-B is saying change it at 39,000, I don't know how often after that.
The Blackstone guy was surprised that some the M-B dealers were doing only a partial change. He said he has some kind of Chevy, and always changes it all but not a flush
. For the main thing, he doesn't need one. Evidently, on whatever he has, you open one plug, and it all drains out. Then you replace the fluid, the filter, maybe a couple of gaskets, and then BINGO - everything is clean again. Our trannys are a different animal, and although a complete change is still possible, it is more involved, and costs more than our partial change did (obviously more fluid, and a higher labor charge).
Bottom line: If I still have this car at 90,000 I'm having the job "done right" then.
