I don't think the power steering fluid runs through the radiator.... I think it's endgine oil on driver side and tranny fluid on passenger side....could be wrong on that though.

In any event, if your radiator is failing you need to get an external tranny cooler installed yesterday. It's a known issue and if the radiator fails on the tranny fluid side you will have a catastrophic failure of your tranny and cooling system. That equals big $$$.
