You will have to swap the '02 engine crank and cam reluctor rings(and use the '02's cam and crank sensors) into your '05's engine and use the '02's intake manifold and exhaust manifolds.Yes this means you have to tear down both engines.You also will need to swap the flexplates as the 45RFE requires and different flexplate then the 42RLE.

If your doing all the work and the stuff is good in the blown '02 engine it's just going to cost you a gasket kit and a lot of your time.
