The gen. IV 5.3 PCM should work with the LS3. And the tranny should be fine..

what yr 5.3 ?what is the count on the reluctor wheel ?check Texas Speed for a long block with the correct reluctor wheel for your ECM .you will need a ECM retune before you fire the engine up.

If you can get your hands on one for the money I personally would do an ls6 swap but if not go with an ls3
