Hi all, I was reading some old threads on preventive maintenance for my 12 C300 Sport and I cant determine which transmission I have. All the vin decoder sites don't tell me much, including the one on here. My car doesn't shut off when stopped at a light, does it mean I have the 7G? I can't tell which color fluid it has either due to the obvious.

427 AUTOMATIC TRANSMISSION 7-SPEEDG
964TRANSMISSION CODE VERSION 64

Also, why does it show its a C280 4MATIC, and not a C300 4MATIC?

Thanks is advance!

If you have A89 REDUCED-FRICTION, from your data card, this means it is a 7G+

You have 7G.

Thanks^^^ I do have that A89 REDUCED-FRICTION option, so hopefully that tells me something?

Anyone else could confirm?

Thank you!

So the A89 reduced friction comment brought up by another member is new to me. I am very surprised to hear if you have the 7G Plus. It may just be worth asking your dealer with the transmission oil change interval is on your car. If it's a relatively long figure (here in Canada, the 7G requires fluid changes every 60,000km, then it's the 7G) then it's the 7G plus (longer than 60,000 = 7G plus just so I'm clear).

Does your C300 have direct injection? How much HP does it make?

There's another thread where we discussed this, but I can't find it but it basically says that A89 automatically means 7G+ but there are 2011 and 2012 cars that don't have A89 when you decode the VIN yet they came filled with the blue fluid meaning it has a 7G+ transmission. In this case, this could be my car which does not have A89, but it's a 2012 C300 4MATIC Sport.

Mercedes claims that they shifted to the 7G+ in 2010-2011 for the W204. I used to think that only cars with the Eco button for start-stop had the 7G+, but based on the above, apparently that's not the only condition to have it.

I will try to dig up that other thread where a popular forum member here told me all this.

If you have the oval holes on the bottom of the oil pan, instead of the round ones, you have a 7G+. My 2011 has the 7G+.

Thanks all^^^ I just called the dealer, not sure why I didn't think of that sooner, and they confirmed I have the 7G. They did a nationwide search and no transmission fluid change/flush was ever performed with them. Also checked carfax and nothing is noted on there in that regard. I just passed 44k so I'm due for one.

Now looking for a reputable German automotive repair shop!

Thank you again!

2012 M276 W204's don't have an ECO start-stop button. As for the 7G+, I've been under the impression that all M276 equipped W204's have 7G+.

I found this online too which confirms what you're saying. When my car was getting an alignment, I got under it and I remember seeing the beveled aft pan too which means it should have the 7G+.

TheRulesLawyer

2012 was a weird year. if you have a m276 you probably have a 7g+ but that means c350 most places. If you have a m272, its possible you have the 7g+ if you have late production. transition years its always worth checking.

I got the chance to get under the car today and inspect the oil pan which confirmed that I have the 7G+ transmission as per the pictures below.
