Hello. I have a 2006 E350. It has 149K miles. This is my first Benz. I noticed when the car engine first starts up and the temperature is below 80, it feels like the transmission jerks when the gear is changing. Would this be a normal thing?

Nope. You can try with a transmission fluid change as a beginning.

Not normal. There is so much information out there on what you can do to try to restore the transmission back to normal. If it were my car, I would start with several drain and refills using MB's ATF fluid that is correct for your transmission, and not some fluid that is supposedly compatible. You have changed the filter inside the transmission? Cleaned the magnets?

Hello,

I have a 2009 E350 and had the same problem 5-6 years ago. No local dealers could fix it. I wound up stopping at a dealership in Augusta, GA, and they did a transmission flush. Have not had a problem since.

Is it the 4matic or RWD? The 4matic was the 5 speed and had a transmission connector/pilot bushing. You can change that when changing the fluid/filter. It uses ATF 134. You can get a case of it at a shell distributor for around $60 for a case of 12 quarts as opposed to the $20+ at the dealership. Otherwise if the fluid change doesn't fix it, could be the conductor plate. The 2006 models all had the bad balance shaft so hopefully yours has already been replaced otherwise I wouldn't spend too much trying to fix this car if that problem is going to pop up.

Thanks to all that responded to my inquiry. I just bought this for my wife for $3500. I had to invest another 1.5K for a catalytic converter. I was looking into trying to change the trans fluid with the kit. It appears the estimate cost for a local dealer could run up to $500.

quick question regarding the ATF 134. If I only drop the pans, change the filter and 4-5 qts or ATF 134.... is it ok for this to mix with old, original MB ATF?? or will I need to flush/replace the whole system with this ATF?? thank you

F1Fan

Doing it that way is fine. But you should really drain and refill another 2-3 times in order to make sure you get all the old fluid out. What I would do is several drain and refill, then on the last drain, replace the filter inside. What is your plan on checking if you have the correct level of ATF fluid inside? The transmission is sensitive to having the proper amount of fluid inside.

F1Fan

You can do it easily yourself. Not really that hard to do.

cetialpha5

Yes, that's fine. Shell ATF 134 is on MB's approved fluid list and you can mix any fluid that's on the approved list. Fluid change interval is about every 40k. If it's been a while, you could change it again after another 10-20k. Getting every old drop out is a little OCD and a little overboard considering the manufacturer doesn't even recommend it. They know that you're only going to get 4-5 quarts out when you're just dropping the pan. You can buy a dipstick separately to measure the fluid level. It's extra long so you can't leave it in afterwards. Originally MB even claimed that it was sealed for life and no need to change it, I guess too many failures changed their mind and they did the 39k recommendation.

Hi, Im capable of doing this job myself. I have done this job few times before. Infact, I repair everything on MB cars myself. Just that for this job, without the lift, laying under the car with limited space is a pain....

nguyenphananh

my cars is 07 with 722.9 tranny so no dipstick (or at least I dont know of... I dont even see the tube). Had to use the complicate and time consuming technique recommended by MB!!

GOD4M3

Are you referring to doing the drain/refill during the same change or changing it and running it for another 10-20k miles then change???

cetialpha5

People who are OCD about getting the last drop out mean in the same change. But if you're really going to do that, search the old threads, people would just disconnect one of the transmission lines and change the fluid until it ran clear. That method took around 12-14 quarts. I think it's overkill as a pan drop and filter change is what the dealer would do.

F1Fan

Something along the lines of doing a drain and refill, drive it 5-10 miles, then doing another drain and refill. I ended up doing quite a few drain/refills to get the color of the ATF to look like new.

GOD4M3

Update to the AAMCO visit. The mechanic say I would possibly benefit for a new conductor plate and value. He also states this is normal for the 722.6 trans. He also told me that the ATF looks good. He also states that doing a ATF change/flush too much could harm the trans rather than benefits. Any feedback would be appreciated.

nguyenphananh

From my research, the 722.6 trans are bullet proof. They RARELY need to fix/replace the conductor plate and valve, if not at all!! The 722.9 tranny are the ones that had conductor plate problems!!. The most common problem for the 722.6 trannys is the electrical connector leaking oil, which lead to short (very easy fix, and should be consider replacement maintenance). My last W202 with 722.6 tranny, ran perfect at 250K miles without problem (when I sold the car for the W211). The connector leaked at 200K, and I replaced it myself for $30. I replaced the tranny fluid on that car every 80K miles. Ran perfect, not a single problem!!

F1Fan

If your car is shifting fine then there is no need to replace the conductor plate. I thought that model year 2006 E350 had the 7 speed, 722.9 transmission. Wasn't 2005 E320 the last year for the 5 speed 722.6 for W211s? Except for the 4Matics that held the 5 speed for a few more years. It would be good to know exactly what kind of transmission you have before you go to a repair shop. If they are recommending a part replacement for a transmission you do not have, then it is obvious you won't benefit from it.

I'd like to second this. I noticed odd/sluggish transmission behavior on my 2005 W211. It had leaked and pumped ATF all of the way forward along the cable harness into the transmission control unit which was full of fluid. It was a mess. Watch those seals and don't ever overfill anything.

My 2007 E550 (147k miles) used to do this on freezing cold mornings. But it would only do it when shifting from 1st to 2nd after pulling out of my driveway. For some reason, it doesn’t anymore and I do not know why but I’m glad because that tells me that whatever it was, it wasn’t mechanical. I have reset the shift adaptations a few times so maybe that was it.
