since my auto kenari radiator is old, i think of disable the original atf cooler in the radiator and totaly rely on an external atf cooler to cool my auto gearbox which will be install in front of the ac condensor..because i heard that the atf cooler in the radiator will eventually crack and allow radiator coolant to flow into the auto gearbox and destroy the auto gearbox...can or not?? pros and cons??
