Hello All:
I was speaking with a service advisor and he indicated that at the 40k service they inspect the transmission fluid and depending on which type of fluid is in the transmission, they will change it or leave it in until 70k miles. Anyone familiar with this? Does anyone know how to tell which type of fluid was/is in the transmission?

Id highly suggest getting it done to get out any break in friction material

Hmm, so based on the info in the other thread, my car probably has tthe 70k mile fluid in it.


7G-TRONIC/7G-TRONIC PLUS (722.9) in the Workshop | Tips und Tricks 53
Oil Work tips
Oil change interval
With the introduction of the NAT2FE+ transmission (7GTRONIC
PLUS), an extended oil change interval applies. This
does not apply to the transmissions with EHS object number
A220 270 00 60 or A220 270 01 60 i.e. it does not apply to
all transmissions which use the blue fluid.

Due to the reduction of friction power and thus heat input
into the FE+ converter (see chapter "FE torque converter"),
the oil change interval of the transmission fluid in the
NAG2FE+ changes from once at 50,000 km to regularly every
125,000 km.

yep dont put atf 134 you need the FE+ blue fluid also you have a different oil tube guide and filter.

Thanks! I don't plan to do it myself yet (unless I get a really high price from a dealer), but this is good info.

my bad the newer models do have the blue tranny fluid.
