I'm comparing things between the 200 series and Tundra. As you know, they share allot of technology and parts design. The Tundra lacks the 200 series lower radiator ATF to coolant heat exchanger. The Tundra does have a very large ATF to air cooler, but it dosn't receive any cooling air flow from the engine fan.... It would be nice to have the extra exchanger as some guys have experienced trans over heat warning while pulling heavy loads at slow speeds (again, no airflow from the fan), this would prevent that.... so, I'm trying to find out the dimensions of the 200 series radiator to see if it is the same size and maybe a direct fit into the Tundra.
