I've had a very small coolant leak coming from the lower transmission line fitting on the radiator. I've replaced the transmission line fitting with new o ring and still dripping, does the big nut behind the trans line fitting have some sort of o ring on it as well, I couldn't turn it and didn't want to get to crazy and break something, or am I looking at a new radiator? Sorry for the rough picture, it's hard to take a picture hold the mirror and the light all at once
