Hi everyone
I have a 2013 c63 amg for not so long and I'm servicing right now my transmission oil and I'm unable to find the bolt for purging the torc converter. Was turning the engine pulley and after two complete turn, no bolt!
Am I missing something ? Is there a purge bolt on those model or I will have to do a second trans purge to get almost new oil in it ?
suposed to have a 722.9 transmission and my vin is WDDGF7HB8DA878177

thanx
David

2012+ models don't have a torque converter

sorry wrong post

Mines a 2011 and doesn't have one either

deadlyvt

if your car is a 2011 it certainly does have a torque converter... unless you have done a transmission swap

Black_Mercedes

I believe Its an early MCT transmission with "A89 Friction-Reduced" Use's the blue fluid" Instead of red.

What's your VIN? If it's it an NA car, are you sure it's not an MY12 that was purchased/delivered in 2011?

Pretty sure P31 may have came with upgraded MCT transmissions?

Jasonoff

That decoder is not accurate. My 2010 VIN says the same thing.

FWIW........
You see the OP is from 2017

Review the following;

The c class didn’t get the mct version until 2012... if your car has one with an mct and it is a 2011 it isn’t the original transmission it’s that simple. No options on a 2011 could have you end up with a mct from the factory in a c63 period

Black_Mercedes

Its pulled directly from vin decoders? as NAG2 Plus

deadlyvt

I don’t know what codes are reading but I’m telling you Mercedes never built a c63 model year 2011 with a mct transmission take that for what it is.

Here is an article that tells you all the differences from the 2011-2012. Somewhere I. There it will state the switch over to the 7 speed mct transmission 👍

Black_Mercedes

Sorry i don't read car and driver. Im going whats based off of vin decorder. Post the Vin of your car and see what the difference is between the two.

Jasonoff

It's not accurate. I 100% for sure do NOT have an MCT.

deadlyvt

No you are right your car has a transmission that was never available for your car because a vin decoder says so.

Jasonoff

Is that why I can't find my TC plug? I have been looking for YEARS!

Jasonoff

LastVIN.com can get you a proper datacard.

For your car: Transmission 722907 02 948362

722907 = non MCT. An MCT is 722930

deadlyvt

haha yes!! For some reason these cars drain plugs on the tc are hit and miss some have them and some don’t not sure why but I have seen both versions

Black_Mercedes

I changed the transmission fluid on my car. There is no port on the bell housing to access any type of bolt.

Jasonoff

Then you couldn't find it or someone changed your transmission.

Black_Mercedes

How could someone not find the port thats on the bottom of the transmission bell housing? That doesn't make any sense.
