transmission fluid lines
 

odd problem on my blazer 4.3... its got magical disapearing tranny fluid! no leaks anywhere and ive gone thru over 3 quarts this week! could it be a leak in the coolant line within the radiator? my fresh dexcool looks a bit milky colored too

Yes, it can definitely leak in the radiator. It usually ends up looking like a strawberry milkshake.

i guess that would explain why my overflow tank is suddenly overflowing huh lol

new radiator fixed this issue
