you are not sopposed to run the lines back into the radiator. well ive never seen anyone run them back kinda defeats the purpose. as far as i know the transmission dosent need to be at a certain operating temp just the engine. if you run the fluid into the radiator its going to heat the fluid back up from the heat of the coolent. like i said ive seen coolers on street cars and strip cars and no one runs them back threw.
