W204 2013 Auto box service interval?

[TRXnMe]

Apologies for asking this, but when I try and search I'm getting an error message about the forum not working

I recently purchased a W204 with the 2.1 diesel engine and the 7 speed automatic gear box, the car is coming up to 75k miles and has MB service history to 46k miles with an independent service about a year ago at £62k and the dealer I bought it from carried out an A service before I picked it up.

While I'm new to MB I know auto boxes are finicky things and are horribly expensive if denied proper care, so what should have been done to my Benz box?

I have come across two service intervals while digging around on here, 37k and 75k, which is the right one?

Is it due for a first ATF change at 75k, or will it have been done, all be it late, at the 46k service? and therefore not be due until 83k miles?

Last question, is the ATF change a job I can trust my usual garage with, or do I take it to my nearest MB dealer who is around 25 miles away? The thought of paying official service rates isn't attractive, but neither is a knackered auto box....

Thanks in advance.

You have the 7G-Tronic Plus (NAG2-FE) gearbox. The ATF change is at 5 years/77,500 miles.

I can't comment on your local garage's ability to do the change satisfactorily because I don't know them. But if they're a Mercedes independent specialist then they should be fine.

Thanks for the information, looks like nothing I'd read was right!!

I have around 2.5k miles to find a suitable service centre based on your advice

My usual guys aren't B specialists, but have been competent with everything I've given them so far, Rover 75 Diesel, Nissan Almera, Freelander Diesel auto, various Fords.

Does anyone have any questions I should ask them to check if they know what they are doing or not? I know autobox services generally require a specific temperature to check the level at, are Mercs the same, iif so what is it? If they know what they are looking for they can probably do the job, I generally trust them but always retain a level of suspicion until proven wrong.....

Find a local indy if I were you. The parts will be the same price as my fella will only fit genuine MB. But labour is £50 an hour. A lot cheaper than main dealer.

Not too difficult to do yourself if your into your cars.

Sounds like I'll take it to the place I bought it from then, they are my nearest MB independent, I was slightly loathe to do this as they have given it an A service before sale when I suspect a B might have been more appropriate, but I understand this is profit related so....

I had hoped my local garage, who I have used for the last 8 years, would be able to handle it, but looking at the cost of good used 7g autoboxes I'd probably be better off looking after the thing properly and leaving 'normal' work to my usual guy

When I bought my July 2008 C220 from MB Ashford (end of March 2012) - supplied new by them to first owner, serviced by them and then taken in PX and sold to me (as 2nd owner) as Used Approved, I had a major row as the owners manual said "ATF change at 37k miles" which had not been done. They said the gearbox on my car was sealed for life and no ATF change was required, it was the later cars that needed an ATF change at 37.5k miles. Depsite my argument that it was in the owners manual for my car, they would not budge! I could not push too hard as I'd made them include a B service due 4 months after I bought the car, in the sale price! Car had <50k miles when I bought it, now has 80k and has not had an ATF change - and seems OK. Might get it done fairly soon "just in case".

I was taught that oil was cheap, engines and gearboxes are expensive.
Get it done!!

I'm not sure if you have already had the transmission serviced TRXnME,

but there are 2 types of transmission fluid for the 7 G-Tronic (722.9),

you will almost certainly have a Blue efficiency and this uses a Blue coloured transmission fluid, make sure you have your transmission filled with the correct oil, the 722.9 doesn't have a filler tube either you have to fill it through the drain plug so getting the level right is not easy to I would either take it to a Merc specialist or a Transmission specialist, this is not a job I personal would trust to a general garage.
