I'm looking ahead and planning to do the suggested Transmission fluid flush/replace. I'm at 72K miles now and was told 75K is a good point to do this job. Has anyone here had this work done at Mercedes? Just wondering what the price tag is for this. Thanks in advance.

I did mine at about 50k miles. Did it myself so don't know about prices. Pretty straightforward for the ZF type of transmissions. I used LiquiMoly but in retrospect I might have stayed with the Penotsin MB fluid. Not that there was a real issue, just a feeling. Good luck with the work.

Thanks Mbwillgrubs. I appreciate the feedback. I'm fairly certain that this type of thing is beyond my ability. I'm going to discuss it with the MB tech when I have the oil, filter and air filters changed in 6 weeks. If the price is too high, I have a local guy who will allow me to purchase the trans fluid myself and pay him for the labor.

Do you recall how much fluid it required??

I don't remember how much fluid. I know the FCPEuro kit has too much. The info is out there somewhere.

I've been looking around to get my transmission fluid flush/replaced and have been quoted anywhere from $389 all the way up to $790. These were local shops, most Euro shops wanted $550 +. Didn't call around to the Mercedes dealer to get a quote. I've done alot of researching, watching videos and plan to tackle this myself in my garage. The kit for new fluid (7 liters), pan gasket, bolts, magnets, filter is anywhere from $150 - $300 depending on where you go.

The refill process is thru the pan on the CL63 (there is no trans dipstick) , if there is I personally have not been able to find one on this 722.9 transmission. once you drain the pan, and put back on , you need to fill thru the pan - put in about 4-5L. Start the vehicle let the transmission get up to temp and then try to put another 0.5 - 1 L into pan. I've heard that the torque converter will hold around 2L of fluid. There is a way to also drain this as well. there is a window in bottom transmission have to spin engine around to find the drain plug on the converter.

Might want to ask who you get quote from if they drain the converter as well. Oh one other thing if its 2012 or newer you need the ATF Blue ( MBZ 236.15) - not the ATF Red that was 2011 and older.

Hope this helped.

Had mine done by an independent for $430. Labor was $200 and parts $230. Took 6 liters of red fluid.

I would also recommend changing the diff fluid as well.
