do any of you guys notice if your c6 shifts weaker in the cold? i have a stock c6 behind a 460 and it seems to shift kinda mushy in the cold, mostly the 2-3 shift. usually an auto shifts harder in the cold. i was wondering if this is common. its a very healthy trans, but im wondering if my cooler is making it run to cold for the winter.

 

did you leave the lines running into the radiator there too when you put your cooler on? That is supposed to help keep it warm in cool weather also.
