Something to watch out for, besides the electrical upgrades which have already been mentioned: more small cores (4) is not better. All that metal interferes with the airflow and the multiple small tubes don't have as much heat transfer capability as fewer large tubes... IMHO the best radiator to use is a two-row with 1.25" or even 1.5" tubes if there is room between the core and the engine.

The additional trans cooler probably helps a bit, but I would not use it instead of the radiator cooler. It'd have to be pretty big depending on the converter...
