Transmission Fluid interval :2013 c250

Hi,

I'm interested in knowing if anyone changes (either forced or drain and fill method) their W204 transmission fluid and when ?

The reason I'm asking is two-fold. 1. On my other car the mfr claimed 'lifetime' transmission fluid which turned out to be total B.S. Coincidentally, that model had infamous transmission issues which I luckily avoided by instituting my own interval program : a once-per year drain and fill.

2. Our C250 was used and I've noticed that other c250s (loaners) drive much more 'smoothly' if you get the sense. i.e. accellerating and coming off of the pedal, I notice more so on our's than other c250's (even of the same model year).

first change 39k, and after that I change mine every 40k. These 722.6 and 722.9 are known to have transmission problems if they are not very well maintained. Trust me it is worth the money if it keeps you from having to get a new transmission.

Remember he has a 2013. If his car comes equipped with ECO mode then it likely has the 7G Tronic Plus and blue fluid that only requires changing every 70k. Always check your manual though.

Sorry to disagree but it cannot be a hotly contested issue when the manufacturer clearly indicated which models should have such service performed at which mileage mark.

I will agree that many on this forum and elsewhere do argue and try to convince others of their own theories, but frankly, and unless they can present credentials that equate to the MB Engineers that designed and manufactured these vehicles, their assessment is not valid by any means as far as I am concerned.

Anyone who chooses to discredit the MB Maintenance Schedule (see below) and instead subscribe to an amateur's theory, is playing with fire and is likely to get burned by the high cost of transmission repair or replacement.

Here is the 2013 maintenance schedule for several MB models and it specifies the required services by engine designation. It does list several MB engines as requiring Transmission oil & Filter change at 40,000 miles for the following MB engine designations: (engine 156, 157, 272, 275). Which then appear to get repeated at the 80,000 mile mark.

Then again, there is another listing for the C-Class @ 70,000 miles along with the following MB engine designations (engine 152, 271, 276, 278, 279, 651).

Great point... I would not compare my car to a loaner, even if its the same model/year. In fact most people who are given a loaner, end up abusing that car while they have it (like a rental). And that might be the reason why it may have felt more spirited in its reaction. It doesn't mean it will perform better for the long term.

Also with regards to this:

I think changing it once a year is going overboard. It certainly is not a cheap service... And to do so at 1/4 the manufacturer's suggested period... Its like changing motor oil at 3500 miles. Nobody does that.

Just my 2 cents.

As I stated. Every 39 or 40k. Personally I wait until 39k max just that way if something happens and dealer does not want to pay or help you, they can't say you didn't maintain the car accordingly. You actually performed the maintenance 1k before there service is called for.

Actually, that model's (my other car, a volvo xc90) major "mis-design" is it's transmission. If you visit the xc90 forums, you'll find ample 1st hand accounts / evidence. Consequently, there are a few conclusions :

1. Since the manufacturer claimed lifetime fluid and there's a class action suit around the xmission (a mfr defect) one can conclude with authority that the mfr's specifications are not always the way to go....

2. Since I have an affected model, i change the xmission fluid once per year. It costs me about $100 since I only pay for the fluid and do the drain and fill procedure myself. I don't need any mechanic. Compare that with the cost of replacing an AWD xmission and any sane person will conclude that it's not "going overboard".

Sure, I could take the mfr's word.... and then deal with the hassle and expense of coughing up $6,000 for a rebuild or replacement, but then... Nobody does that.
