It will probably be fine for a while. You should make sure your current radiator is clean and free of obstructions, though. For the investment, aluminum radiators are well worth it.

You just need a small transmission cooler for your TH350. I usually put mine off to the side in the grille cavity, so it doesn't block the air to the radiator.
