C63 204 and C63 205 gearboxes?
Greetings MB Massive,
In my last C63, A 125 coupe when pushed it would go into limp mode when the gearbox got too hot, VERY Annoying!!
I Now have a New C63 205 and do you know if the fault remains and if so should i get a gearbox sump extension to carry more oil and thus run cooler?
ie this? http://weistec.com/722-9-transmission-pan.html
Cheers RG.

Mine runs about 183 deg in normal summer driving and up about 10-12 deg in spirited mountain driving with no limp mode ever.

Never had a problem with the trans. Skip that transmission pan, it’s a money grab for stock and even tuned power levels. It’s only folks with upgraded turbos pushing over 1000 NM that start to have issues with the trans slipping. And I’m fairly certain it’s trans clutch plates need to be beefed up at that point, not this larger capacity pan.

Depending on my driving style my trans sits at about 185 just cruising. If i do a couple pulls depending on my driving style i’ve seen my tran temps go up to 210F, most i’ve ever seen was 264F and that was after 4 consecutive rolling burnouts 😂

9G-Tronic (codename 725.0) is Mercedes-Benz's trademark name for its nine-speed automatic transmission.[1] This transmission was introduced in 2013. It is the world's first nine-speed transmission. It was first used in the Mercedes-Benz S-Class (W222), and it has been expanded to be used in the Mercedes-Benz C-Class (W205) and the sedan and wagon variants of the Mercedes-Benz E-Class (W213). Plug-in hybrid and V12 engine models continue to use the older Mercedes-Benz 7G-Tronic transmission. Wide ratio spread of 9.30:1.
google this tranny to understand the heat transfer improvements. think of riding a bike uphill, with higher gears versus one with more gears to choose from and how that helps you reserve energy. Works the same for machinery. more energy used to propel, more heat generated. nespas?
