Replacing automatic trans of 2002 Kia Sedona cause the engine not to start?

What is your question?

I replaced automatic trans on a 2002 Kia Sedona , I made sure all connections are correct, now engine does no start. Engine was running so very smooth and beautiful before replacing the trans. Can you say where to look, ECM, etc.

How long has your 2002 Kia Sedona had this problem?
