I am about to break-in my engine after a major overhaul. The engine(390) and tranny(C6) are installed but I have not run my tranny coolant lines yet. Also I have not added any transmission fluid to the tranny, just one quart required for the torque converter installation. The car will not be put in gear during break-in. Will this be a problem, like will this fry the transmission, or do I need to run the lines and add the required amount of tranny fluid before break-in?
