But, we all know it is NOT a true race car, but better yet a street car that can handle track duty.

I would say that when my transmission kicked me out of M mode, I wasn't too surprised...it was very hot as I mentioned before, and I only know of a few other street legal cars that could have gone as long as I did without overheating something in those conditions. IIRC the track temp was in the 130's....So, I guess my point is that it's no wonder the C63's are having the same issues under even more favorable conditions as they are not setup to take the abuse that the Black Series can handle. Again, someone should looking into putting the CLK Black Series transmission cooler setup in to the C63. Im sure it would be an easy intall and you'd have all factory parts - the only thing I could see being an issue is fitment and space. You would probably have to have a few brackets custom made and perhaps move a few lines around.

To the OP - what was the ambient temp while you were running ? You cannot just "get more airflow" or use another trans fluid to keep this from happening. If you do plan on tracking your car more you REALLY need a larger transmission cooler or an additional one installed in the left bottom bumper cover as ATL MB suggested. If there is space there, that's what you should do.

Also, if your car has an ECU tune AND you are planning on headers and a pulley...I'd strongly suggest going with an additional trans cooler. Take a look at ths thread and you will see what I mean:

But don't be surprised when ***** starts to break. Really tracking a car is AMAZINGLY hard on every component...from tires, to brakes, to axles, transmissions, every part of the motor, suspension and steering - it's a brutal environment. Sure, it may be fun, but it's also EXPENSIVE.
