Hi guys, I'm hopefully to take delivery of a 2011 pre-facelift C63, and to my understanding all PFL's use a torque converter (TCT). Initially I thought all TCTs use the red fluid/white overfill tube, but ECS tuning is showing that cars with code A89 REDUCED-FRICTION, which my will have, use the blue fluid.
is the cutoff not as simple as Pre-facelkift=TCT=Red fluid/white tube, and facelift=MCT-blue fluid/green tube?
no unfortunately its not as simple as that. you need to look up the build sheet on your vin number and see if it has the A89 option "reduced friction". If it has that then you use the blue fluid. If not then you will use the red fluid.
for example my prefacelift 2011 uses the blue fluid.

Just look at the transmission pan. small indentations is the old pan with white overfill tube (red fluid). larger indentations is the newer transmission pan with the green overfill tube (blue fluid).

Thanks. My confusion was that I thought torque converters trans used the red fluid, but my VIN is showing A89 which is blue fluid. (car is still in transport so I can't check yet, soon hopefully)

Be careful someone hasnt upgraded to the larger pan.
